Sanitary Pneumatic Butterfly Valve

Product Detail

Description & Application:    Sanitary pneumatic butterfly valves consist of a stainless steel pneumatic actuator and butterfly valve body. Driven by compressed air, the pneumatic actuator accordingly control the butterfly valve body to open and close, in order to control the flow rate of hygienic fluids. Sanitary pneumatic butterfly valves can realize remote operation and reduce much human working load. They are usually used in the pipelines where is far away from control unit or places with very limit access to manual operation, as well as systems in need of very frequent open/close operations. Stainless steel pneumatic actuator butterfly valves are the ideal choice for extremely anti-corrosion applications. Material:
