Max. working pressure: 145psi (10bar) for DN25/1"-DN100/4".

Operation: SS304 vertical actuator, NC (normally close) / NO (normally open) / AA (air to air) type for choose from.

Air supply pressure: 70-116psi (5-8bar)

Temperature range: 14 ~ 248°F (-10 ~ 120°C) with EPDM seat, -58 ~ 356°F (-50 ~ +180°C) with VMQ (Silicone) seat.

End connections: thread / thread.

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.
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, 3A, SMS, ISO / IDF, BS / RJT, and ASME / BPE
