Type 27511 - 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 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.  |
