Type 27512 - Pneumatic Actuator - Globe Valve (on/off)
Overview - required actuator sizes for differential pressures
|
Pneumatic Actuators for Globe Valves (on/off) 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. |
