Type 27522

CRYOGENIC

Type 27522 - 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
"cleaned and degreased for oxygen service"
Ambient temperature limit:
-40°C / -40°F (233K) 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.
