Sanitary Hygienic Pneumatic Actuator Butterfly Valve

Product Detail

Description & Application:    Sanitary pneumatic butterfly valves consist of a aluminum alloy 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. Comparing with vertical stainless steel pneumatic actuator, horizontal aluminum alloy pneumatic actuator is much lighter, and more economical due to lower cost. Sanitary pneumatic butterfly valves can realize remote operation and reduce much human working load. They are widely used in the pipelines of nearly all hygienic industries such as food, brewery, beverage, cosmetics, pharmacy and so on. Material:
Pneumatic Actuator: Aluminum alloy, horizontal installation
Valve Body: Medium contact part: SS304 or 316L upon customer request
Other Part: SS304 Or other stainless steel material on request
Sealing Gasket: EPDM, PTFE, VMQ, NBR or FPM for your free choice
Surface Polish: Mirror polish, sand blasting, electric finishing, etc.
Working Principle: The valve closing and opening is operated automatically by the pneumatic actuator. The actuator is driven the compressed air going into and out of the actuator. Double acting: Air in–Piston outwards–Valve stem rotates–Valve open–Air in again– Piston backwards–Valve closed Spring return single acting: Air in–Piston outwards–Valve stem rotates–Valve open–Piston backwards automatically by spring–Valve closed Specification Details:
