Materials of Construction 

Thermoplastics 

PVC (Polyvinyl Chloride) 

The most economical and largest selection of Chemline 

valves are moulded from PVC. It offers excellent mechanical 

and chemical resistance properties at low cost. The working 

temperature range of PVC valves is 0 to 60°C (30 to 140°F). 

PVC used for Chemline valves is identified by cell classification 

number 11564-A as per ASTM Standard D 1784. The suffix 

“A” refers to the highest chemical resistance rating. Most 

other PVC valves as well as pipe and fittings have only a “B” 

chemical resistance rating. 

The special PVC “A” compound used in Chemline valves 

resists attack of most acids, strong alkalais, salts and many 

other chemicals. High chemical resistance of this material 

allows its application on aggressive services such as 98% 

H2 SO4 , dry chlorine and low pressure wet chlorine gas. PVC 

is attacked by chlorinated hydrocarbons, ketones, esters and 

some aromatic compounds. It can be used on solutions 

containing up to 1000 ppm solvents. 

Chemline PVC valves are non-toxic. They meet CSA standard 

B137.0 for toxicity. 

They are resistant to damaging effects of sunlight and 

weathering, thus painting is not necessary. 

CPVC (Chlorinated Polyvinyl Chloride) 

CPVC is very similar to PVC in mechanical properties and 

chemical resistance. It is suitable for applications from 

0 to 95°C (30 to 200°F). 

The special CPVC compound used for Chemline valves is 

classified as 23567-A as per ASTM D 1784. The suffix “A” 

denotes conformance to the highest chemical resistance 

rating. The compound is non-toxic, conforming to CSA 

toxicity standard B137.0. 

CPVC valves have proven to be an excellent choice for 

applications at temperatures too high for PVC or when an 

extra margin of safety is required. 

PP (Polypropylene) 

PP is light weight and high in chemical resistance. Valves are 

suitable for service from –20 to 90°C (–5° to 195°F). PP is 

unaffected by alkalais, salts, organic solvents and most acids, 

particularly hydrochloric and phosphoric acid. It is unsuitable 

on strong acids, chlorinated hydrocarbons, aromatic 

compounds and high concentrations of free chlorine. 

PP is very inert thus popular for high purity applications such 

as deionized water, etc. The material comes normally 

opaqued by addition of grey-beige pigment to prevent 

ultraviolet light penetration. Natural translucent material 

without pigment will degrade if exposed to UV light (sun 

light). Chemline offers PP pipe, fittings and valves in 

pigmented and unpigmented PP, both approved by the FDA 

for contact with food. 

PVDF (Polyvinylidene Fluoride) 

PVDF is superior to other valve thermoplastics in chemical 

resistance and abrasion resistance. It has remarkable strength 

over the largest working temperature range. The working 

temperature range of PVDF valves is –40 to 120°C (–40 to 

250°F). 

PVDF’s impact strength is over twice that of PVC. The valves 

are extremely durable under mechanical abuse even at –40°F. 

They also offer the highest abrasion resistance of 

thermoplastic valves. 

PVDF has excellent chemical resistance against halogens such 

as chlorine and bromine, strong acids such as hydrofluoric 

and nitric acids, organic solvents and oils. PVDF is not 

resistant to hot bases. 

It is also non toxic and imparts no odours or tastes into the 

fluid. Our PVDF conforms with USDA Title 21, P121.2593 

requirements for contact with food. 

Gas permeability of PVDF is extremely low. A patented PVDF 

gas permeability barrier is available on Type 14 and DV Series 

Diaphragm Valves. It is a backing to the Teflon ® diaphragm 

and has proven to increase the life of diaphragm valves on 

chlorine and strong acid services. 

Teflon ® PTFE (Polytetrafluoroethylene) 

PTFE is almost totally insoluble and chemically inert. It has 

high temperature resistance. Teflon ® PTFE ball seats, because 

of natural lubricity, require no lubrication. Teflon ® PTFE 

diaphragms and flange gaskets are used in the most severe 

chemical resistance applications. 

Elastomers 

EPDM (Ethylene Propylene Terpolymer) 

EPDM is a synthetic rubber used as the standard seal material 

for most Chemline valves. It is the most economical choice of 

elastomer and has excellent chemical resistance on the great 

majority of applications including acids, alkalais, salts and 

many others at temperatures up to 90°C. EPDM is weak on 

organic compounds and cannot be used on oils and fats. 

Chemline valves seals of EPDM meet CSA standard B137.0 for 

non-toxicity. 

FKM or FPM (“Viton ® “ Fluorocarbon Rubber) 

FKM/FPM is more expensive than EPDM so is used as an 

alternate elastomer when required. It has excellent resistance 

to mineral acids, oils and many aliphatic and aromatic 

hydrocarbons. FKM/FPM (Viton ®) is weak on sodium 

hydroxide. 

FKM-C is a special formulation with higher resistance to 

chlorine services. 

FKM-F offers better chemical resistance on inorganic acids 

than standard FKM. Ratings are included for hydrochloric, 

nitric and sulphuric acids. 

CPE (Chlorinated Polyethylene) 

CPE is superior to all other elastomers on sodium 

hypochlorite. It resists hypochlorite up to full strength (13%). 

Ball valves supplied with CPE seals are very price competitive 

on this service. 

NITRILE (Acrylonitrile-Butadiene Copolymer, abv. NBR) 

Nitrile is also know as Buna-N. It has high chemical resistance to 

oil and petroleums but is weak on oxidizing media i.e. acids. 

Nitrile has excellent abrasion resistance and is less expensive 

than FKM/FPM (Viton ®).

Chemline SG Series Gauge Isolators allow inexpensive 

pressure gauges, or any other pressure instrument to be 

used in corrosive services. The upper chamber (gauge 

side) is filled with a stable fluid such as glycol or 

glycerine‡. A diaphragm separates it from the lower 

chamber which receives the media under pressure. 

The 1/2" gauge connection allows use of the popular 4" 

and 4-1/2" diameter gauges. Pressure switches or 

transmitters may also be installed. Customers can easily 

fill isolators and install their own gauges.

AR Series 

Air Release 

Valves 

The Chemline AR Series Air Release Valve allow gases 

to escape from unpressurized pipe lines. It must be 

installed vertically at the highest point in the piping 

system with the “Air” arrow up. As the unpressurized 

air vents, liquid rises to the float (an inverted cup), 

which lifts the float up against the seat, holding liquid 

pressure. The float will not release until the pressure on 

the inlet side of the valve is equal to the outlet pressure 

of the valve (normally atmospheric). 

Low Cost 

Sizes up to 3" 

Features 

Full Size Range 

● 1/2" to 3" 

Large Flow Capacities 

● Valves have full port liquid capacities, so for air flow 

they may be chosen several sizes smaller than the 

liquid pipeline. 

Outlet Cap Available 

● For non-hazardous fluids, the optional removeable PE 

outlet cap prevents tampering with the union nut. 

Eliminates possible splashing during quick closure and 

covers the open end. 

● For hazardous fluids, a 3 foot pipe should be installed 

on the outlet side or the outlet should be piped to a 

containment area.

AA Series 

Air & Vacuum 


The Chemline AA Series Air and Vacuum Release Valve 

provides a controlled venting solution for larger 

diameter piping systems. This valve reduces the 

potential for water hammer incidents that occur when 

pressure builds up due to entrapped air. A unique twostage 

ball stop prevents liquids from escaping while 

allowing high volume air release while the pipeline is 

under pressure, also at low pressure when it is being 

filled. 

The vacuum release function allows air to re-enter the 

pipeline to prevent vacuum collapse. 

PDCPD (Polydicyclopenthadiene) is a polyolefin 

thermoset plastic. Valve parts are manufactured by a 

process called reaction injection moulding (RIM). 

PDCPD has excellent corrosion resistance and 

temperature ratings, very similar to those of 

polypropylene. It is durable material offering very high 

impact strength and a fraction of the weight of cast 

iron.

Back Pressure/ 

Relief Valves 

The Chemline SB Series Back Pressure/Relief Valve 

has two functions. As a back pressure valve, installed 

in-line downstream of a pump, the back pressure 

below the metering pump is maintained. When 

installed in the branch of a tee it is a pressure relief 

valve. The valve stays closed until inlet pressure 

reaches the set pressure which is adjusted by turning 

the spring tensioning bolt. The “Mini” SB17 size 

relief valves offer high performance in a compact 

package.

SB 10/11 Series 


Relief Valves 

The Chemline SB Series Back Pressure/Relief Valve has 

two functions. As a back pressure valve, installed in-line 

downstream of a pump, the back pressure below the 

metering pump is maintained. When installed in the 

branch of a tee it is a pressure relief valve. The valve stays 

closed until inlet pressure reaches the set pressure which 

is adjusted by turning the spring tensioning bolt. Inlet 

pressure acts on the Teflon ®control diaphragm opening 

the valve, allowing excess pressure to flow downwards 

through the orifice. 

The SB10/11 Series is very sensitive to pressure changes 

and requires low overpressure to fully open. It is 

designed for clean fluids only. 

Sensitive and Reliable 

Designed for Long Life 


Features

OVER PRESSURE VS. FLOW RATE 

The curves show the relationship between the over 

pressure (inlet pressure above the set pressure) and 

the approximate flow rate through the valve for 

water at 20 O C (68 O F). These values vary depending on: 

● The configuration of the piping and the pressure 

losses associated with it. 

● The fluid if not water at 20 O C (68 O F). 

● Whether the pressure is rising or falling. Hysteresis is 

approximately 4 psi.

SB 12 Series 


Relief Valves 

The Chemline SB Series Back Pressure/Relief Valve has two 

functions. As a back pressure valve, installed in-line 

downstream of a pump, the back pressure below the 

metering pump is maintained. When installed in the 

branch of a tee it is a pressure relief valve. The valve stays 

closed until inlet pressure reaches the set pressure which 

is adjusted by turning the spring tensioning bolt. Inlet 

pressure acts upward against the piston allowing excess 

pressure to flow upwards through the orifice. 

The SB12 Series has a built-in check valve function, 

desirable for dosing applications. It is not so sensitive as 

to open with every pulsation from a metering pump. 


Ideal for Chemical Dosing Systems 

Built-in Check Feature

Pressure 

Regulating 

(Reducing) 

Valves 

The Chemline SR 50 Series Pressure Regulating 

(Reducing) Valves maintains a set downstream 

pressure independent of higher variable upstream 

pressures. As downstream pressure increases 

reaching the set pressure, the valve closes. It opens 

as soon as the downstream pressure decreases 

below set pressure. 

The SR 50 is sensitive and provides precise control. 

One application is to protect filters from damaging 

pressure surges.

Pressure Regulating Valves 

HOW THEY WORK 

The SR 50 controls downstream pressure, which must 

always be below the inlet pressure. It is normally 

open until the downstream pressure (which acts on 

the control diaphragm) reaches the set pressure, 

adjustable with the spring tensioning bolt. At this 

point the valve closes. It opens again as soon as 

downstream pressure decreases slightly below the 

set pressure. 

The large diaphragm provides for sensitive and 

precise control. The valve seat opens and closes until 

a balance is achieved between the spring force (set 

pressure) and the downstream pressure. 

WORKING PRESSURE VS. FLOW RATE 

The curves show the relationship between the 

downstream pressure below set pressure and the 

approximate flow rate through the valve for water 

at 20 O C (68 O F). These values will vary depending on: 



● The fluid if not water at 20 O C (68 O F). 

● Whether the pressure is rising or falling. Hysteresis 

is approximately 3 psi.

End Connectors 

All Chemline valves with True Union ends are 

available with ChemFlare TM end connections. 

ChemFlare TM is a long term leak-free connection 

design for difficult applications such as sodium 

hypochlorite 1 . These flared end connections are easy 

to install and allow for compact plumbing and a 

small footprint. 

They are available on Chemline True Union valves, 

flow meters and controls up to1" and will connect 

Teflon ® PFA tubing down to 1/4" size. 

Tubing must be flared using a mechanical flare tool 

or by heating and using a forming flare tool 

(preferred method). Consult Chemline for flare 

tools.

Low Down Time 

Features 

Weldless Design 

● Eliminates all fusion welds and glued joints 

● Threaded connection between flared end and 

tube nut is not wetted 

Easy Installation 

● Flaring the tube ends is easy 

● Assembly is by hand 2 

Low Down Time 

● No welding or curing waiting time. The system

Characterized 

Control Valves 

The Chemline E Series Characterized Control Valves provide 

extremely precise flow control of aggressive fluids. Valves 

flow characteristics (Cv vs. lift) follow theoretical linear or 

equal percentage curves through the entire range of stem 

travel. This is accomplished with precision made 

replaceable seats and plugs in a wide variety of Cv values. 

The Teflon ® bellows shaft seal provides almost frictionless 

stem movement and provides over 10 years of 

maintenance-free operation on aggressive chemical 

services1 .

EK Series valves – FRP Actuator – 90 psi maximum supply air. 

The actuator will close the valve tightly against higher line pressure drops, up to 90 psi depending on the Cv. 

ACCESSORIES FOR EK SERIES 

Positioners – YT Series linear valve positioners are usually used 

on all EK Series pneumatically actuated control valves, They 

control actuator-valve stem position as a linear function of 

input signal, usually electronic (most often 4–20 mA) or 

sometimes pneumatic (3–15 psi). Valves with Cv 9.5 (PVC & PP 

valves) and Cv 10.5 (PVDF & PTFE valves) or lower may be 

operated with the 3–15 psi signal directly without a positioner, 

but the linearity is compromised. The standard units have 

epoxy coated aluminum enclosures but are available in 316 

stainless steel. All available models are attractively priced: 

● YT1200R 3–15 psi Pneumatic – a conventional all-mechanical 

positioner 

● YT1300R 4–20 mA Electro-Pneumatic – an electronic 

positioner designed for vibration resistance, better control 

and easy calibration

Variable Area 

Flow Meters 

Chemline F Series Variable Area Flow Meters are 

ideal for plastic piping. They provide a combination 

of accurate visual flow rate measurement and clear 

flow indication from a distance. Optional limit 

switches allow the units to signal a low or high flow 

alarm. An optional flow transmitter provides a 

4 to 20 mA signal output. These flow meters must 

be installed vertically with flow upward. 

Low Cost Visual Indication 

For Water, Chemicals or Gas 

Features 

● Clear Visual Indication 

– Large orange float is visible from a distance 

– Range indicators slide along dovetail track 

● Easy Installation and Maintenance 

Just unscrew union nuts and tube slides out 

of line 

● Choice of Four Tube Materials for Many 

Applications: 

Clear PVC – For Water or Chemicals up to 

60ºC (140ºF) – High Chemical resistance at 

low cost. 

Polyamide (PA) – For Water or Air up to 

75ºC (167ºF) – High impact strength and 

optical clarity. 

Polysulfone (PSU) – For Chemicals and 

Gases up to 100ºC (212ºF) – High impact 

strength and good chemical resistance. 

PVDF 2 – For Chemicals and Ultrapure fluids 

up to 110ºC (230ºF) – High impact strength 

and excellent chemical resistance. 

● Ideal for All Types of Plastic Piping 

All types of end connections in PVC, CPVC, 

PP & PVDF 

● Low Pressure Drop 

● Good Measuring Accuracy – Class IV 

± 3% of indicated value, plus ± 1% of full scale. 

– Read scale at top (largest diameter) of float 

● Non Fouling – Float is self supporting in the 

flow. No guide rod (which can cause the float 

to jam) is necessary. 


Standard 

Full Size 

1 USGPM and litres per hour (water) scale is supplied as standard on full size meters. 

2 Because PVDF is translucent, a magnetic float and limit switches are usually used.

ACCESSORIES 

● Limit Switches – One switch for both 

maximum or minimum. A magnetic float is 

required. 

● Switch Ratings – P (max) = 10 VA, 

E (max) = 470VAC, I (max) = 0.5A 

● Throttling Valve for flow control 

● 4–20 mA Output Signal Unit must be factory 

calibrated for specific service 

OPTIONS 

● Custom Direct Reading Scale for services 

other than water 

● Alternate O-Rings – ie. FPM (Viton ®) 

● End Size Reduction – Accuracy is not 

significantly affected by end reduction 

● Other Ends – Threaded, socket or flanged 

end connections in PVC, CPVC, PP or PVDF. 

Butt ends in PP or PVDF. 

Flow Meter Sizing – Liquid Flow 

Standard Scale values are for clean water flow at 20ºC (68ºF). For liquids with densities and viscosities similar to water (ie. specific gravity of 

1.0 and viscosities between 0.5 cP and 1.3 cP) the standard water scale will be accurate enough. 

The table below shows correction factors to be applied for liquids with specific gravities other then 1.0. Multiply the correction factor by the 

water scale value to obtain actual flow rate. Example: For a liquid of specific gravity of 1.66, the correction factor is 0.740. For water flow 

range of 100 to 1000 litres/hr, corrected range becomes 74 to 740 litres/hr. Viscosity should be between 0.5 cP and 1.3 cP for standard scales 

to be accurate. 

For "sizing" liquid flows ie. determining actual flow range of a tube, please advise the chemical name, concentration, temperature, specific 

gravity and viscosity. Custom direct reading scales in any units are available special order.

SCALE CORRECTION FACTORS – FOR AIR AT NON-STANDARD TEMPERATURES AND PRESSURES 

Air density is dependent on the actual pressure and temperature. 

Calculate the Scale Correction Factor using either Method 1 or 2. Multiply the 

standard air flow ranges above by the Factor to obtain actual flow rates. 

Method 1 

Calculate the Factor with the following formula. 

Factor = 1 psia 

3.7005 (1+0.00367t) 

psia = pressure of the air absolute 

= psig + 14.7 (atmospheric pressure = 14.7 psia) 

t = temperature of the air ºC
