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 Air supply - maximum 6.0 bar g Body - Steel (1.0976), coating - acrylic 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. |
