  • Butt-weld connection type
  • Clamp connection type
  • Thread connection type
  • Aluminum actuator and weld end
  • Aluminum actuator and clamp end
  • Aluminum actuator and thread end

Applications:
Sanitary pneumatic butterfly valves are designed to open and close in order to control the flow rate of fluids in hygienic systems like those used in the production of beverages such as wine, dairy, beer, purified water, pharmaceutical liquids, biological mediums, etc. They are installed in all kinds of sanitary and hygienic facilities, pipe lines, and equipment such as:

1. C.I.P. (clean in place) facilities and systems
2. Liquid purification, filtration, blending and mixing systems
3. Production and recycling system of purified water, highly purified water, water for injection (WFI)
4. High gravity brewing systems
5. Aseptic dosing systems, sterilization systems, sanitary batching systems, evaporation systems
6. All kinds of hygienic pipe systems and equipment

Materials:
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: free choice from mirror polish, sand blasting, electro finishing, etc.

Working Principle:
The valve closing and opening function is operated automatically by the pneumatic actuator. The actuator is driven by compressed air going in and out of the actuator.
A. Double acting: Air in--Piston outwards--Valve stem rotates--Valve open--Air in again-- Piston backwards--Valve closed
B. Spring return: Air in--Piston outwards--Valve stem rotates--Valve open--Piston backwards automatically by spring--Valve closed
