hydraulic valve actuator / rotary / double-acting / for gas
Gas/Hydraulic Valve Actuators (often referred to as Gas over Oil type) use a high pressure gas supply (typically 300 to 1480 psig) as their power source. Often used in gas/transmission pipelines in which the pipeline media is used for the actuator's power source. Actuators are available in rotary (1/4 - turn) and linear versions and can be supplied with practically any required control system including remote control and linebreak systems.
