Pinch Valves

Pinch valves are more commonly used for flow control in processes with the purpose of opening and closing. Since the rubber liner, which is the primary element of the valve, is a piece of rubber pipe with flanges for fixing purposes at its ends generally with fully cylindirical structure, it is very suitable for flow control thanks to its higher flow coefficient (Kv) and lower loss coefficient (ζ) than other valves.

The rubber liner, which is the most vital and important element of the valve, works successfully under high wear conditions.

Pinch valves are produced in two types as open casing (carcassed) operating at lower pressures and closed casing for higher pressure applications. The flow rate can be precisely adjusted by closing and opening the rubber liner on the pinch valve with a special screw shaft. Pinch valves are produced in different diameters as both closed type aluminum cast body and open type steel casing.

Pinch valves can be manually controlled or operated with a PLC controlled air actuation system, for example, to provide level controlled flow in processes. Pinch valves suitable for automation are also produced upon request.
