2021 wholesale price Spring Return Actuator - HPR-SR – Hankun

The HPD high performance linear pneumatic diaphragm actuator adopts multi-spring structure, which make it with light weight, small volume and large output force. Its working principle is that the air source pressure enters the diaphragm chamber and acts on the diaphragm to generate a thrust, which causes the actuator push rod to move, and at the same time compresses the spring until it balances with the reaction force of the spring, so that the push rod reaches a predetermined position. HPD series linear actuator is suitable for linear motion control valve, proportional adjustment and on-off valves, and other linear motion devices etc.
