Pinch valves,the simplest valve design,include any valve with a
flexible elastomer body that can be pinched close to cut off
flow,using a mechanism or fluid pressure.They are linear motion
valves that can be used to start,stop and throttle media through a
system.Pinch valves are low maintenance,low weight,and can be used
in systems requiring explosion proof line closure.While the design
of pinch valves provides extensive advantages for use in sterile
lines and in situations where product purity is a high
priority,these same design features do create some
disadvantages.Due to their elastomeric bodies,pinch valve is not
viable in situations where the transport media is at a high
temperature.They are also not recommended for services that require
high pressure flow,and for use with gases.
Advantages
1. Very Clean
2. Excellent drainage
3. Minimal turbulence
4. Low airborne contaminants
5. Low maintenance
6. Low weight
7. Can be used in explosion-proof lines
8. Inexpensive
Disadvantages
1. Cannot be used in high temperature applications
2. Cannot be used in high pressure applications
3. Cannot be used with gas media
Method of Control:
1. Pinch valves use a liner motion method of control.
2. The disc is a flexible material liner,similar to a
diaphragm.
3. The stem of the pinch valve has a free-moving connection to a
moving closure bar,called a compressor,which is located directly
above the liner.
4. As the hand wheel is turned,the compressor lowers the liner to
squeeze the liner against the bottom support to close the
valve.
5. The pressure of the media in the valve can help in starting or
stopping the flow.
