Actuators are electric-powered devices that allow pipeline operators to operate valves. Electric, air (pneumatic), or flow power (hydraulic), which in our instance is gasoline or gas, can all be used. Two types of actuators are available: temporary and rotating. Gas-over-oil actuators move the mechanics of the actuator by suspending the high pressure gas in the pipeline with a hydraulic fluid. Double-acting gas-over-oil actuators are the only ones that can be used. A power source provides electricity to electric actuators like a battery. Precision control of product flow through valves is critical in the oil, gas, and petrochemical industries, and the valve actuator is responsible for this modulation.
