Pneumatic diaphragm control valve

The L1000 Series pneumatic actuator is a multi-spring diaphragm actuator with such features as light weight, small volume, stable output force, etc. Through acting on the diaphragm inside the actuator, the air supply conquers the reverse action force of the spring and makes up ward and downward linear movement. When there is no air pressure, the compression spring releases pressure and pushes the push shaft of the actuator to move upwards or downwards. The actuators of this series can be classified into direct action type and reverse action type .

According to different diaphragm effective areas and travels, the actuators include the following 5 specifications:

The action principle of the L2000 linear motion multi-spring piston pneumatic actuator is the same as that of the multi-spring diaphragm actuator. But the L2000 Series actuator replaces the diaphragm by piston, which has solved the problems of the diaphragm actuator being unable to bear relatively high air pressure and easy ageing of the diaphragm, and the actuator can bear higher air pressure. The increase of the air pressure has enhanced the output force of the actuator. The standard configuration is single acting type. Double acting type actuator can also be designed according to the need .

According to different piston diameters and travels ,the actuators include the following 4 specifications:
