Since the early days of gas transmission pipelines, critical safety-related valves have used the pipeline gas to operate a fluid power valve actuator. Most of these automated valves are located remotely, so there is a lack of alternate power sources. Fluid powered actuators use either a compressible gaseous substance (including instrument air) or a non-compressible fluid to pressurize a chamber in the actuator to create a linear thrust or rotary torque output.
