General Design Considerations 


A butterfl y valve is a type of fl ow control device, typically used to regulate a 

fl uid fl owing through a section of pipe. A fl at circular plate (disc) is positioned 

in the centre of the pipe. The plate has a rod (shaft) through it connected 

to an actuator on the outside of the valve. Rotating the actuator turns 

the plate either parallel or perpendicular to the fl ow. Unlike a ball valve, the 

plate is always present within the fl ow, therefore a pressure drop is always 

induced in the fl ow regardless of valve position. 

A butterfl y valve is from a family of valves called quarter turn valves. The 

“butterfl y” is a metal disc mounted on a rod. When the valve is closed, the 

disc is turned so that it completely blocks off the passageway. When the 

valve is fully open, the disc is rotated a quarter turn so that it allows unrestricted 

passage. The valve may also be opened incrementally to regulate 

fl ow thanks to the gradual interlocking notch. 

Butterfl y valves are of simple design, of light weight and volume and very 

effective on isolating lines for its quick and safe operation. Most of butterfly 

valves design are fl angeless for installation between counter fl anges what 

saves space, costs and maintenance. 

There are two kind of fl angeless butterfl y valves: 

Wafer Style Butterfl y Valves: Wafer style is the more common one and is 

lest expensive one. The wafer style butterfl y valve is just about the standard. 

It is so common that no one even bothers to use the word “wafer” 

when ordering a butterfl y valve. They take it for granted that if they order 

a butterfl y valve, they will get a wafer style one. Wafer butterfl y valves are 

installed between two fl anges using bolts or studs and nuts. This type of 

installation, of course, makes it impossible to disconnect just one side of 

the piping system from the valve. That is where the lug style valve comes 

in. 

Lug Style Butterfl y Valves: Lug style valves are provided with tapered holes 

to fi x threaded bolts in. This allows them to be installed into a system using 

two sets of bolts and no nuts. The valve is installed between two flanges 

using a separate set of bolts for each fl ange. This set-up permits either side 

of the piping system to be disconnected without distributing the other side. 

Lug Style Butterfl y Valves are used in dead end service and generally have 

a reduced pressure rating. 

Valves can also be of dual fl anged design; provided with integral flanges 

that are ready to be installed between fl anges of the same standard. These 

are more bulky valves and usually required for large sizes and other styles 

of performance by the position of the shaft. (see next paragraph). 

Other kind of valves by its nature of shaft design are as follows: 

Concentric Design: This is the most common and simple design. The valve 

shaft is concentric to the disc. It is normally a resilient seated valve. Rotating 

the handle turns the plate either parallel or perpendicular to the flow of 

water, shutting off the fl ow 

Double Centric Design: This design features a slight offset in the way the 

disc is positioned, which increases the valve’s sealing ability and decreases 

its tendency to wear. It is normally used for throttling functions, larger sizes 

and / or metal seated valves. 

Triple Offset Design: This design is the one offering a highest degree of 

performance. The shaft is totally off set from the central axis thus increasing 

the ability of the valve disc to close tightly at even high pressure. These 

valves are usually metal seated thus being used for high temperature too. 

These valves are usually operated by worm gear to achieve a slow closing.

General Design Considerations 


There are some common parts innate to butterfly valves regardless 

of its design, brand or materials of construction as follows: 

A Body; this is the main framework of the valve which houses the 

moving components of the same. It is made of metal and can be of 

diverse styles as mentioned above. 

B Liner; it is a rubber or plastic circular seat inserted into the body 

inner part and can be either vulcanised or made of an insert. The 

vulcanised type cannot be removed once assembled whilst the insert 

can be replaced at any time. The liner provides the required 

tightness to the valve. 

C Shaft; it is the rod that drives the disc by rotation. It can be made 

of two piece rod (without pin) or a single piece rod (with pin) depending 

the way to assemble and disassemble it. 

D Disc; It is the plate which is guided by the shaft and blocks or 

allows the fluid to pass. It is the closing element of the valve. 

E Packing; set of soft goods that provides the atmospheric integrity 

to the valve. Usually are provided with a shaft packing in the upper 

part and the bottom bush in the lower part. 

F Notch plate; it is the metal position indicator and gear locking 

fi x on top of the valve neck where the actuator is supported. The 

function is locking the actuator in intermediate positions if needed. 

G Actuation; it is the component which actions the valve, it may be 

a hand lever; usually used for quick action and standard sizes; a 

worm gear box; used for slower action and large valve sizes; pneumatic, 

electric pr hydraulic actuators; for remote and continuous 

operations. 

H Name Plate; not innate to the valve design but of equal importance 

as it is providing the user all design and working parameters of 

the valve. It is normally affixed onto the valve front neck by riveted 

aluminium plate.

Basic Operating and Maintenance Guidelines. 

Butterfl y Valves are bidirectional and can also be installed in whatever position being along the horizontal or vertical pipe work 

axis. It is recommended to fl ush the pipe work system out with valves fully open before start up. Valves thermal insulation can be 

easily carried out thanks to the extended neck design as standard, this makes easier the task to insulate the valves by means 

of the aluminium rigid material. 

Replaceable seat Butterfl y valves are relatively easy to maintain. The resilient seat is held in place by mechanical means, and 

neither bonding nor cementing is necessary, Because the seat is replaceable, the valve seat does not require lapping, grinding, 

or machine work. The job can be done at the plant operator by having the adequate tools to carry out this service. 

If, otherwise, valves are of vulcanised seat, these have no possibility to be serviced although the low cost of the valve would not 

suggest to do it. 

The actuation is quickly dismounted and replaced if needed. All valve top works are normally designed to comply with ISO 5211 

standard that guides the dimensions to be followed in order to adapt actuators with full versatility. 

This engineering manual illustrates all the UNIVAL® range of butterfl y valves, one of the largest portfolios of butterfl y valves presently available 

for isolating and regulating duties. It is comprehensive of diverse styles and materials of construction and offers an in-deep study to the superb 

design and performance availed by the more than a million units installed all over the world.

Flow Data 


A valve fl ow coeffi cient represents the standard flow rate which flows through the 

valve at a given opening, referred to pre-established conditions: 

* Kv value is the volume of water at 20ºC, in cubic meters per hour (m3/h), that will 

flow through the valve at a static pressure drop of 1 bar across the valve 

* Cv value is the volume of water at 60ºF, in gallons per minute (gpm), that will flow 

through the valve at a static pressure drop of 1 psi across the valve 

Conversion from Kv to Cv can be roughly calculated by means of the following expression: 

Cv = Kv x 1,17 

Flow rate through the valve with other liquids can be calculated with the following 

expressions (for gases please consult us) 

Kv = q (SG / dp)1/2 

where 

q = water fl ow (m3/h) 

SG = specifi c gravity (1 for water) 

dp = pressure drop (bar) 

Cv = q (SG / dp)1/2 

where 

q = water fl ow (US gallons per minute) 

SG = specifi c gravity (1 for water) 

dp = pressure drop (psi) 

It is common practice to size the valves on the basis of pipe DN for on off application. 

Nevertheless, Butterfl y Valves used for control purpose should be calculated on the 

basis of operating conditions. 

First step is to calculate the Kv values for the different working conditions and then 

choose the DN with such Kv values in the region of 20º to 70º valve opening angle. 

As a general guideline, fl ow velocities should under certain limits, so as to avoid 

valve excessive noise, vibration and cavitation: 

Liquids: < 4,5 m/s; Gases: < 100 m/s

Grooved Ends Butterfly Valves 


UNIVAL® Grooved ends butterfl y valves are concentric 

valves which offer reliable service in all water works 

duties. Valves are bi-directional and can be installed in 

whatever position. The grooved ends design allows the 

contractor to tie the valves onto the pipe work with grooved 

couplings thus saving signifi cant costs in fl ange and 

bolting kits. Grooved couplings are very common on the 

water sector what requires from valve manufacturers to 

design ends to accommodate this fl ourishing demand. 

UNIVAL® butterfl y valves are at the forefront of this requirement 

with the newly launched type VF-760. Other 

equipment is being added up to the grooved end design 

such as strainers, gate valves and check valves. 

These valves have an excellent fl ow control with low 

pressure drop. The valve design is simple, of light weight 

and volume and very effective on isolating lines for its 

quick and safe operation. The gradual lock hand lever 

design allows to lock the valve at intermediate positions 

thus making it possible to control de amount of fl ow. 

Salient attributes of the UNIVAL® Grooved ends butterfly 

Valves: 

1.- Body; long neck to allow isolation in HVAC duties, 

precisely cast, cleaned and machined grooves to allow 

perfect coupling of groove clamps. Body is externally and 

internally EPOXI coated to offer better environmental resistance. 

Seat less design; no slot to accommodate the 

disc. 

2.- Shaft; Two piece shaft (without pin), easy dismantling. 

Made of polished stainless steel 420. 

3.- Disc: Fully encapsulated rubber disc. Engulfs the 

shaft and tights the valve. Can be of EPDM for water 

service or NBR for other fl uids. 

4.- Packing; EPDM or NBR set of O-Rings placed at the 

upper and lower parts of the shaft providing good atmospheric 

integrity to the valve. 

5.- Notch plate; Cast Aluminium position indicator and 

gear locking fi x on top of the valve neck. Locks the lever 

in intermediate positions if needed. 

6.- Actuation; Hand lever is the standard up to DN 300 

whereas worm gear box is used for larger sizes.

REMARKS FOR ACTUATOR SIZING: 

The torque values given are for water or other non-viscous lubricating liquids at ambient temperature 

For butterfl y valves with PTFE or other non elastomeric seat, multiply above values by 2 

Recommended safety factor to be applied: 25-35% for double acting pneumatic actuators 

30-50% for single acting pneumatic actuators and electric actuators 

There are several factors that can increase above given values and should be taken into account for actuators sizing: 

-For gases and dry medium (non lubricating), multiply above values by about 1,25-2 depending on application 

-For viscous liquids increase above values depending on the liquid properties 

-For unusual service conditions such as likelihood of seat swelling, or low and high temperature seat hardening, 

and additional safety factor should be considered. 

There are three torques to be considered when selecting the proper actuator for a butterfly valve: 

1) Seating Torque: The torque to displace a resilient seat and effect shutoff. 

2) Bearing Torque: The torque required to overcome friction forces on the valve shaft bearing surfaces during valve 

travel angle (about 30% of seating torque) 

3) Dynamic Torque: Due to fl uid forces which tend to close the valve when the valve is partially open. This torque is 

due to the velocity of the fl uid created by a differential pressure across the valve. Systems should be projected 

to avoid high velocities across the valve 

Above given values are inclusive of the 3 torques, the actuator selected must provide the calculated torque over its total 

opening and closing travel angle.

PNEUMATIC ACTUATORS CMVL B Series - Operating Principle - Air Consumption - Weights 

DOUBLE ACTING TYPE 

Standard Rotation: 

Air to port A forces the pistons outwards, causing the pinion to turn counterclockwise 

while the air is being exhausted from port B. Air to port B forces 

the pistons inwards, causing the pinion to turn clockwise while the air is being 

exhausted from port A. 

Reverse Rotation: 

Air to port A forces the pistons outwards, causing the pinion to turn clockwise 

while the air is being exhausted from port B. Air to port B forces the pistons 

inwards, causing the pinion to turn counterclockwise while the air is being exhausted 

from port A. 

SINGLE ACTING TYPE 

Standard Rotation: 

Air to port A forces the pistons outwards, causing the springs to compress, the 

pinion turns counterclockwise while air is being exhausted from port B. Loss 

of air pressure on port A, the stored energy in the springs forces the pistons 

inwards. The pinion turns clockwise while air is being exhausted from port A. 

Reverse Rotation: 

Air to port A forces the pistons outwards, causing the springs to compress, 

the pinion turns clockwise while air is being exhausted from port B. Loss of air 

pressure on port A, the stored energy in the springs forces the pistons inwards. 

The pinion turns counterclockwise while air is being exhausted from port A.

PNEUMATIC ACTUATORS CMVL B Series - Operating Conditions and Instructions 

1. Supply: Dry or lubricated filtered compressed air, non-corrosive gas or oil 

2. Air supply pressure: Double acting : 2 to 8 bar (29 to 116psi) 

Spring return : 2 to 8 bar (29 to 116psi) 

Highest pressure: 10 bar (145psi) 

3. Operating temperature : Standard (NBR O-ring) : -20°C to 80°C (-4°F lo 176°F) 

Low temperature(Silicone O-ring): - 35°C to 80°C (-31°F lo 176°F) 

High temperature (Viton O-ring): -15°C to 150°C (5°F lo 302°F) 

4. Travel adjustment : Have adjustment range of ± 4° for the rotation at 90° 

5. Lubrication : Standard grease MoS2. Under normal operating condition, 

no need for additional lubricant for at least 1 Million manoeuvres 

6. Application : Either indoor or outdoor 

COMMISIONING 

Remove any manual operating device from the valve, leaving the valve stem clear. Make sure that the shape 

of the stem fi ts the actuator bore and the rotation is not hindered in any way. Mount the actuator on the valve, 

inserting the actuator bore well on the stem. Make sure that the rotation direction is correct; in any case do not 

insert your hands inside the valve. We strongly suggest checking the cleanness of the air-supply pipes and 

ensure to that it is properly fi ltered. A spacer between actuator and valve will be necessary with fluids at high 

temperature. 

MAINTENANCE 

- It is recommended that periodic checks are performed to make sure that all fasteners remain tight. 

- The actuator supplied is readily lubricated and no further lubrication is required. If lubrication is deemed necessary, 

use MoS2 grease. 

- Under certain working conditions (heavy duty, non-compatible operating media or abnormal operating conditions) 

internal seals should be checked periodically and replaced when necessary. 

- On spring return actuators, spring fatigue may set in requiring the replacement of springs. Springs should 

always be replaced in full sets. 

- If an actuator is properly assembled and used, it will be maintenance free, as it has been lubricated enough 

to last a normal working life under normal working conditions. Should it be necessary to replace the seals, our 

recommendation is to send it back to us for repairing and testing. On request, we can supply repair kits and 

instructions.

MULTIVOLTAGE REVERSIBLE ELECTRIC ACTUATOR L&H SERIES 


Main Design Advantages 

L&H Series is the new concept ¼ turn multivoltage electric actuator that finally offers all the solutions that utilize the 

reversible electric actuators for the operation and control of the valves. 

The actuators have been designed using the most current technology available to obtain a product where the operation 

security, economy in cost and releases life has been the principal objective. 

The range is comprehensive of 6 models for each “L” & “H” range covering the following operational torques: 20, 

35, 55, 85, 140 and 300 Nm. 

L&H Series have the following STANDARD features: 

ATC AUTOMATIC TEMPERATURE CONTROL: 

An internal 4 W thermostatically controlled anti-condensation heater maintains the internals between +20ºC and 

+30ºC, (68ºF – 86ºF) eliminating the possibility of damage by condensation. 

AVS AUTOVOLTAGE SENSING: 

The actuators are, within the voltajes ranges specified for “L” or “H” Series, multi-voltage capable and make automatic 

internal adjustments to ensure the actuator operates, irrespective of the power supply 

“L” series operates from 12 to 24V AC or 12 to 24 V DC 

“H” series operates from 85 to 250V AC or DC 

ETL ELECTRONIC TORQUE LIMITER: 

Continuous electric monitoring of the motor produces smooth operation and accurate control of the motor consumption 

up to the maximum permisible torque. Should the maximum torque be exceeded, the ETL automatically cuts 

the power to the motor to prevent damage to the actuator, and automatically relaxes the gearbox to allow simple 

operation of the manual override. 

MO MANUAL OVERRIDE: 

For emergency manual operation, operated by a selector lever on the side of the actuator, with automatic motor 

power tripping when selected. 

PES PROTECTED ELECTRICAL SUPPLY: 

This take 2 forms; firstly the actuator is protected againts shorcircuit when connected and whilst the actuator won’t 

operate if incorrectly connected, no internal damage will result, and secondly, the J3 accepts the same wiring connection 

for either AC or DC operation (grey connector). 

External DIN plugs eliminate the need to remove the actuator’s cover to connect. 

VCO VISUAL CONTROL OF OPERATION: (this feature only available in some models) 

A constantly lid of the external LED indicates the normal operation of the actuator. 

- A fl ashing LED frecuency 1 advises that the actuator’s torque limiter has been exceeded and the ETL has activated. 

- A fl ashing LED frecuency 2 advises that the actuator is in MANUAL position. 

VFC VOLT FREE CONTACS: 

1 set of open and closed volt free contacts are provided as standard.

MULTIVOLTAGE ELECTRIC ACTUATOR - How it works 


Actuator connection to 

valve (bottom view) 

On receipt of a continuous power signal, the motor runs and via a flat gear box system, rotates the output shaft. The 

motor is stopped by internal cams fi tted the output striking microswitches, which cut the power to the motor. When 

a subsequent continuous signal is received, the motor will turn in the opposite direction, reversing the direction of 

the output drive

MULTIVOLTAGE ELECTRIC ACTUATOR - MAIN ACCESORIES 


DIGITAL POSITIONNER 

The DPS 2005 is a device for the J3 electric actuator that turns the actuator 

in a valve positioner servo controled. 

The DPS 2005 is a modulus with a microprocessor (CPU) which manages 

digitally the analogical input and output and compare them with the position 

of the actuator to stablish an uniform relation. 

The analogical inputs are sent to CPU where they are processed for his 

continous comparison with the position of the actuator, this allows to obtain 

a very high sensitivity next to a very high repetitivity of the position (see 

characteristics). 

The DPS 2005 in communication with the electronic system of the actuator 

provides an integral management of the motion on the actuator. 

The DPS 2005 is available for the ”H” and “L” series. 

Main Advantages and Features 

Automatic Reset 

Automatic Setup 

Possibility of using the DPS 2005 for regulations 90º, 180º 

and 270º acted on the setup only. 

Input signal: 4 - 20 mA / 0- 10 V 

Output signal: 4 - 20 mA / 0- 10 V 

Precision: better than 1% 

Settings: max - min. 

Lineality: better than 1% 

Hysteresis: better than 1% 

Min. resolution: better than 1% 

SAFETY BLOCK SYSTEM 

The BSR safety blok system is an automatism that when couple to the 

L & H Series multivoltage electric actuators lets the valve situate in a 

prefereable position NC or NA when there is a power supply failure. 

Inside of the housing actuator there are BSR’s print circuit board and the 

battery pack which are kept in continuous charge. 

In case of the valve is not in the prefereable position and there is the 

power supply cut, the BSR system returns the valve back to the prefereable 

position by means of the batteries tension operating as a “single 

acting” actuator.

Installation, Start-Up and Maintenance 


A butterfl y valve is a type of fl ow control device, typically used to regulate a 

fl uid fl owing through a section of pipe. A fl at circular plate (disc) is positioned 

in the centre of the pipe. The plate has a rod (shaft) through it connected 

to an actuator on the outside of the valve. Rotating the actuator turns 

the plate either parallel or perpendicular to the fl ow. Unlike a ball valve, the 

plate is always present within the fl ow, therefore a pressure drop is always 

induced in the fl ow regardless of valve position. 

A butterfl y valve is from a family of valves called quarter turn valves. The 

“butterfl y” is a metal disc mounted on a rod. When the valve is closed, the 

disc is turned so that it completely blocks off the passageway. When the 

valve is fully open, the disc is rotated a quarter turn so that it allows unrestricted 

passage. The valve may also be opened incrementally to regulate 

fl ow thanks to the gradual interlocking notch. 

Butterfl y valves are of simple design, of light weight and volume and very 

effective on isolating lines for its quick and safe operation. Most of butterfly 

valves design are fl angeless for installation between counter fl anges what 

saves space, costs and maintenance. 

UNIVAL® Butterfly Valves are devised to stop the flow of liquids 

and neutral gases. The valves close by turning the disc 90º clockwise. 

The valves can also be used as throttling design by fixing the 

lever in intermediate positions by means of the gradual lock gear. 

The valves are engineered to match standard operational duties, in 

the event of special duties such as aggressive or abrasive media, it 

is the plant engineer and / or purchaser responsibility to check that 

the selected valve be suitable to the application as well as the dimensional, 

pressure, temperature and material compatibility parameters. 

UNIVAL® butterfly valves are designed, manufactured and tested in conformity 

to the most strict quality standards that the DIN EN ISO 9001 standard dictates. 

All valves are subject to individual hydro and leakage tests at our QC Dept in conformity 

with EN 10.204 / 2.2. The testing medium is water at room temperature. 

Each manufacturing lot is strictly controlled by our Quality Section at the plant 

before dispatch. Extensive reports as per EN-10.204/3.1B are fi lled out and 

are submitted to the Purchase if required. Moreover, witness testing carried out 

by Notify Bodies are arranged upon request at our modern Testing Facilities. 

All valves are provided with a Declaration of Conformity 

in conformity with PED 97/23/CE (to European destinations). 

Please consult our Data Sheets for specifi c information about the valve performance 

details. Factory reserves the right to alter or implement new product 

modifi cations at any time. Our Data Sheets can be freely down loaded via

The guarantee coverage does not apply to eventual damages caused by operation under duties other than the stated with the order 

specification. 

Our guarantee Coverage does not cover for any commissioning or in site maintenance jobs or either products proved to have been 

tampered or faulted by material wear down. 

The buyer is responsible to check that the in-coming product is received in good condition and in conformity to the ordered specifications, 

otherwise an immediate complain must be issued to the carrier or our Company at +34 961479011. 

# – ESSENTIAL SAFETY GUIDELINES. 

- Do not install the valves before having carefully read this Operating Manual in order to avoid prospective damages to people and 

property. 

- Always use the valves within the scope of intended service and operating duties as per described in our data sheets, essential 

safety working regulations are to be strictly kept. 

- Only qualifi ed personnel should start up and regularly follow maintenance jobs at the plant. 

- Any deviation from the usual installation guidelines should be notified to us for recommendation and approval. 

- Whenever the valves are transferred to a third party, this manual or corresponding reproduction should also be handed and 

translated into the corresponding language. 

# – PRESERVATION, STORAGE & TRANSPORTATION 

- Avoid temperatures below –20ºC or above 40ºC, high environmental humidity or corrosive environment. Keep the valves away 

from dust, fl ames or rain to avoid rust of the valves surface. 

- All valves are primed coated by a paint layer against corrosion during transport and storage, do not harm this layer. 

- Avoid hitting or external vibrations, specially on the weak components such as levers or worm gears as well as damaging the 

rubber seats. Do not pile up excessive weight. 

- Do not use fragile parts such as hand wheels or levers to lift up or pull valves. 

- Always use right handling equipment, weights are stated in the Data Sheets. 

# – INSTALLATION 

Bear in mind the following guidelines along with general installation practices: 

- Allow for enough space to ease maintenance operations. 

- Remove the protective caps if they were still fi t. 

- Ensure that the valve internal is dust free and no foreign matter had came in. 

- Protect the valve rubber seats from heating caused by welding works at the plant during commissioning. 

- These valves are generally bi-directional , otherwise, please check the flow arrow and valve marking. 

- Avoid gradients, excessive rotation and pipe misalignment that could cause pipe stress once installed in the pipe work. Counter 

flanges should fi t smoothly. 

- Stem can be installed in any position exception taken from valve DN 350 and above (horizontal stem position). 

- Same as with preservation and storage do not use fragile parts such as hand wheels or levers to lift up or pull valves. 

- Tightness gaskets are not required between the valve and the pipe counter flanges. The valve rubber facing is used for this 

purpose. An excessive tightening onto the rubber facing could cause damages leading to further leakage, it is recommended to 

tightening bolts diagonally and gradually. Increase the torque before final start up. 

- Valves should be installed with open disc. The disc should not come out of the valve profile. 

- All steam systems in the plant should be designed to prevent condensate depots which could lead to water hammers 

- Should valves are to be operated by actuators, follow the instructions given in the specific actuator manual. Should the stem 

position was horizontal, anchoring should be required depending of the complete valve and actuator assembly weight. 

- Once the valve installed, make an initial opening and closure manoeuvre to check their proper performance. 

Project engineers and contractors are responsible for the proper placement and commissioning of the valve.

#. – START UP 

- Before start up, ensure that the material, pressure desing, temperature design, flow direction and other essential parameters are 

correct in conformity to the process. 

- Ensure that the valve is place in its correct position before tightening the final assembly. 

- Observe all local regulations concerning the labour risks and essential safety protection at the plant. 

- Temperatures above 50ºC or below 0ºC may cause personnel injures if valves are touched. Ensure that the corresponding warning 

signs are displayed in the valve or surrounding site.. 

- Avoid remains of welding and dirties fl ushing through the system as it would damage the valve seating if trapped between disc 

and seat. 

# – MAINTENANCE AND REGULAR CHECKING. 

Maintenance and corresponding intervals should be defined and scheduled an by the plant operation personnel according to service level. 

It is highly recommended to operate the valve at least once a month. 

Please review the valve seat surface and the fl ow passage as well as the stem packing. 

Always wait the valve medium to cool down before starting any maintenance job at the plant, release the pressure from the system, 

drain the line and pipe system in the event of toxic, corrosive, flammable or caustic fluids. 

Vale rubber seats are replaceable. However, given the reasonably low cost of the entire valve thanks to the serial and bulk production 

it is not economically wise to replace seats in small size valves. Should seats are to be replaced, please get in touch with our 

specialised personnel for technical assistance. 

#- RECOMMENDED SPARES. 

The recommended spares should be defined in view of the installation magnitude, duties, nº of cycles and other usual parameters. As 

recommended spares only soft goods such as seat and packing should be kept at the plant. In the long term, spare discs and stems 

might also be recommended at user’s choice, however, butterfly valves are highly serialised manufactured items at relatively low cost 

thus complete valves might be used as replacement. 

# – TROUBLE SHOOTING CHART 

SYMPTOM LIKELY REASON CORRECTIVE ACTION 

No fl ow Valve disc is closed Open the valve disc 

End covers still placed. 

Remove end covers. 

Little fl ow The valve disc is not open enough. Keep on turning the hand lever or worm gear. 

Upstream strainer basket clogged with dirties. Clean / replace the spare basket. 

Clogged pipe lines. 

Check pipe lines. 

Atmospheric Leakage Stem packing seals are damaged or worn down. Remove the valve from the line and place a new one. 

Flange rubber facing is scratched or worn down Remove the valve from the line and replace the rubber seat.

Mateial Selection Guidance 


The below chart is intended to provide the end user and valve selection staff with a useful guide to material compatibility. 

No contractual responsibility is accepted by our company as result of wrong use of this list of compounds and materials. 

It has to be born in mind that the process may change behavior depending on other parameters such as pressure, 

temperature, concentration, fl uid velocity…etc. The Valve materials are wide in their specification, i.e: Iron foundry refers 

to Cast Iron A126 or other grades, Ductile Iron and other Iron alloys. Carbon Steel applies to A216 WCB however other 

cast steel alloys such as LCB, WCC have to be interpolated between this cast steel and the superior Stainless Steel. Other 

materials and elastomeric compounds not covered in this table can be advised by our technical team.
