1、Straight stroke multi-spring diaphragm pneumatic actuator is characterized with light weight, small size, high performance, easy to install and so on.
2、Through the film sealing, the pressure of the gas source is on the tray, and in the same time, the compressed spring moves and gas source pressure take effect on the effective area of the tray to produce the thrust force on or up or down. Without gas pressure, the thrust force is released from the spring recovery to move, driving the push rod up or down.
