WebOct 17, 2024 · The actuator receives the force of the pneumatic signal through a top port. Then, it distributes the signal across the actuator’s diaphragm. As a result, the diaphragm exerts pressure on the diaphragm plate. This moves the valve stem downward in a way that strokes the control valve. Electric Actuated They are motor-driven devices. A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves.
