The desired product pressure is reached by supplying compressed air to the pneumatic actuator. A welded stainless steel bellow is used to hermetically seal the product area from outside contamination. This special design and the durable valve seat seal, made of Tefasep®, enables optimum process security. Back-pressure valves are commonly used in pasteurization and sterilization plants.

Actuator
Aseptic back-pressures valves are equipped with an air-closing / air-opening (LL) pneumatic actuator.
Clamp
