Standard Design:

working environment temperature**0°~*0 ° /air pressure 0.2~0.6Mpa(Max.0.8Mpa),Oil-free bearing is added at the sliding friction part to enhance service life.

Working Principle:Single function(spring reset)

Compressed air from the air intake(A)to enter into the space between the cylinder and the reversing accessory piston(B).made the plunger separate and move to the bottom of vylinder,force the spring

compressed,the air of cylinder is distcharge through the vent(C),made the piston(B) anti-clockwise *0 dergree rotation through guide grroove drive Reversing master device(D)in the meantime .(means valve opened)

After the solenoid valve for compressed air backward,the piston(B)cylinder move to the top under the elastic spring.The air of middle air cacity is discharge through the air pipe connector by solenoid valve.At that moment the piston(B) clcokwise *0 degree rotation through the guide groove drive Reversing master device(D).(means valve closeed)
