Type 27512 - Pneumatic Actuator - Control Valve

Pneumatic Actuators for Control Valves

Actuator -
spring to open
, air to close maximum air pressure for operation 6.0 bar g Actuator coating outside - Epoxy resin

Available options - on request only:

- Pneumatic actuator with override handwheel
Ambient temperature limit:
-20°C / -4°F (253K) up to +80°C / 176°F (353K)

The differential pressures are based on the flow direction of the valve. Differential pressures against the flow direction have to be requested separately.
