CRYOGENIC

Type 27515 - Pneumatic Actuator - Control Valve

Pneumatic Actuators for Control Valves

Actuator -
spring to open
, air to close maximum air pressure for operation 6.0 bar Actuator coating: Delta Seal GZ (silver-grey) Corrosion-protection class C5-M acc. to DIN EN ISO 12944

Available options - on request only:

- Pneumatic actuator with override handwheel
Ambient temperature limit:
-40°C / -40°F (233K) up to +100°C / 212°F (373K)

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