Linear actuator is a mechanical control device that converts energy (electrical, pneumatic or hydraulic) into linear motion (up/down, open/close). The product is specially designed to operate globe valves, diaphragm valves, slide valves and devices that require precise push-pull strokes.
Working principle:
The transmission creates linear motion (linear) instead of rotary motion. When receiving the control signal, the thrust shaft will move in the translational direction to open, close or adjust the valve opening level. Depending on the type, the device may operate by electric, pneumatic or hydraulic.
