Sanitary Flange Butterfly Valves Application:
AV-1PF series is pneumatic type sanitary butterfly valve with Flange / Flange ends, which is widely used in process piping systems for isolation and control. AV-1PF butterfly valve operates automatically.
Sanitary Flange Butterfly Valves Options:
- Valve body and disc material can be AISI 304 or AISI 316L materials are available upon request.
- The seat and gasket can be EPDM, VMQ (Silicone) or Viton (FPM), all complying with FDA 21CFR177.2600.
- End connection can be butt-welded, sanitary tri-clamp, threaded, flanged, I-line or others upon request.
- Handles: 4-position pull handle; multi-position handle with plastic cover or in pure stainless steel.
Actuators to reach automatic operation: pneumatic stainless steel actuator (vertical type), pneumatic aluminum actuator (horizontal type), and electric actuator.
- NC operated: normally closed (fail closed)—air to open, spring to close
- NO operated: normally open (fail open)—air to close, spring to open
- AA operated: double acting—air to open, air to close
- Valve intelligent control: position sensor, C-top controller, C-top controller (AS-I)
- Standards: DIN, SMS, ISO / IDF, BS / RJT, and ASME / BPE
