Process and Hygiene
The use of Handtmann butterfly valves has been proven effective for decades in
many areas of the food and beverage industry. Safe function with daily operation
– in conjunction with many years of reliable service – is what sets this valve type
apart from the rest.
The variety of valves, which can be combined with a control and adjustment unit
if necessary, provides the optimum valve solution for many applications. Butterfly
valves are a cost-effective alternative to distribute and block off fluid and gaseous
processing media.
The Handtmann butterfly valve was structurally revised according to EHEDG
guidelines. The modified product area geometry, the materials used and the
surface quality play a role in achieving a good level of cleanability, which is
confirmed by the institute testing the product.
Reliable and modern – Improved, hygienic construction
and design for even more process and product safety
Design in detail
Safety in detail
Its structural task is to ensure contamination-free operation during
production and CIP cleaning. Microbial deposits and chemical
residue can be prevented in the product area.
This has a crucial effect on these requirements and the subsequent
product quality through the switching functionality of the
butterfly valve. Here the Handtmann know-how lies in the details
and is difficult to recognise at the first glance.
■ Minimizing of the mechanical-dynamic load of the seal
■ Optimum coordination between the sealing
geometry and the installation situation
■ Sealing behaviour with temperature changes
taken into account
Handtmann uses the established EPDM material for its shaped
packing. A standardised, consistent elastomer quality is a
prerequisite to ensure switching functionality, hygiene and the
service life.
■ High abrasion resistance, good antifriction properties
■ High chemical and thermal resistance
■ Good form stability, minimal volume swelling
Mechanical safety as part of the process
■ Reinforced valve shat for torque transfer
■ Forged valve disks with a favourable flow form
■ Increased pressure blow resistance and closing seal
Biological safety as part of the process
■ Optimised vapour geometry
■ Cleanability according to EHEDG guideline
Cost-effectiveness
■ Long service life of seal
■ Seal shape can be used in older valve types
■ Rotary actuators can be disassembled or repaired
■ Small maintenance costs

Butterfly valve types
Switch function manual
Switch function pneumatic
Standard butterfly valves Leakage butterfly valve
Handtmann butterfly valves are manufactures as different models. Actuation
can optionally be via a manual lever or via the built-in pneumatic actuator.
Possible monitoring of the switch positions is via a proximity switch or a
control head.
■ Butterfly valves with different process connections
■ Intermediate clamp execution, easy removal of the 2-part valve body
■ Multi-way combination, short discharge with good CIP cleanability
Whatever your needs – Handtmann delivers the
ideal butterfly valve for your application
The easiest type of operation is manual. The different adaptation
possibilities of manual actuation are suitable for all installation
positions.
■ Manual lever with integrated 8 x 45° ball stop,
■ 360° round switch-over, locking optional
■ Manual crank for various settings
■ Bolt-on set for proximity switches
The butterfly valves can optionally be equipped with a pneumatic
actuator. The entire nominal size range is covered with 3 actuator
sizes. The actuator with the standard model is spring-closing/air-opening,
other models are available on request.
The switching state of a single butterfly valve is clearly defined via two
possible end positions. They can be recorded via the proximity initiator
or the control head.
■ Actuators are spaciously dimensioned for high torques
■ Integrated assembly points for proximity switches
■ Actuator versions with a settable stroke limitation
■ Actuator versions for the control head or position controller
If safe, mechanical media separation is required, leakage butterfly
valves can be used. This cost-effective valve type consists of two
valve disks arranged in succession. One of the valve disks is controlled
via the actuator, the other has forced mechanical control.
The leakage area is equipped with a rinse and leakage valve when
the valve position is closed.
■ Switch function manual or pneumatic
■ Safe media separation
■ Limited switching loss
■ Intermediate clamping execution

Process automation
Hygiene and automation are closely interrelated. The high demands placed on
quality and quantity can mostly only be met with automated processes. The
complex processes with a variety of process components require an ever-growing
number of "intelligent" control components.
Depending on the requirements, here Handtmann offers different high-quality
control and adjustment components for valve control, monitoring and process
visualisation.
This makes the process reasonable and documentable. User friendliness
and process safety are considerably improved.
Demanding solutions for a smooth flow – Handtmann valve technology
with intelligent control components adapted to the process.
Proximity switch
Control head V.CON
The easiest, most cost-effective way to monitor the switching
position. Assembly is sideways under the actuator or with a bolton
kit on the bottom with manual actuation.
The newly developed control head V.CON is also available for the
Handtmann actuators. Depending on the control head model,
it takes over pneumatic control, recording and acknowledgement
of the switch positions and the monitoring and acknowledgement
of programmed diagnosis and service functions.
■ "High-end" electronics
■ Contact-free, inductive distance measurement system
■ Large, clearly visible LED domed display
■ Easy commissioning
■ Independent determination of the switch positions
■ Service and data interface
■ Connection 24 V, AS-I
Position controller FLOWfix
The intelligent position controller FLOWfix is especially adapted to
the Handtmann actuators. Many tasks in the fluid and gas control
area can often be performed with simpler, more cost-effective solutions
with acceptable precision.
The prescribed adjustment range of the butterfly valve is "intelligently
linearised" through adjustment factors dependent on nominal
sizes. This adjustment principle allows an adjustment tolerance
of 0.5 – 2.0 % depending on the medium.
■ Cost-effective, compact adjustment value
■ Control of fluids and gas / CO ²
■ Housing with display and touch screen
■ Connection 24 V, signal 4 – 20 mA
■ DP profile bus interface
