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 cylinder,force the spring
compressed,the air of cylinder is discharge through the vent (C),make the piston(B) anti-clockwise 90 degree rotation through guide groove 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 cavity is discharge through the air pipe connector by solenoid valve .At that moment the piston(B) clockmise 90 degree rotation through the guide groove drive Reversing master device(D).(means valve closeed
