Pneumatic piston valve actuator
GE Energy, Valves - Control & Safety
GE Oil & Gas offers a range of pneumatic piston-type actuators for use with globe and linear stem motion control valves. Piston actuators typically provide longer strokes and higher thrusts compared to spring-diaphragm designs, including. Masoneilan Model 67/68, Model 84/85/86, and Model 51.
Small size and weight with high thrust capabilities and enhanced control valve responsiveness to handle higher pressure drop and tighter seat leakage applications
Smaller air volumes allows for faster response and increased actuator dynamic stiffness, providing quick opening/closing speeds and more stable performance in high pressure drop conditions
Flexible design and construction of the stroke length, fail-safe mechanism, and manual override system provide customers with an optimized actuation solution to meet a variety of control valve applications
