Application:
pneumatic type sanitary butterfly valve with butt-welded /
butt-welded ends, which is widely used in process piping systems
for isolation and control. AV-1PW butterfly valve operates
automatically.

356°F (-50 ~ +180°C) with VMQ (Silicone) seat.
End connections: butt-welded / butt-welded.
Surface treatment: Ra 16 ~ 32µin (0.4 ~ 0.8µm), Ra 32µin is the
default.
Options:
Valve body and disc material can be AISI 304 or AISI 316L, 304L and
316 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.

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)
