Type 27521 - Pneumatic Actuator - Control Valve
Overview - required actuator sizes for differential pressures
|
Pneumatic Actuators for Control Valves Actuator - air to open, spring 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. |
