Operation

Standard type (QEV3 － 04 － 15A)

❶ Backpacking 

Air entering port A forces the backpacking to open and flow to port C. When the air from port A is discharged, air from port C closes the backpacking and flows to port B.

❷ Valve 

With an air pressure from port A, the valve is moved, closing port B, and the air flows to port C. When pressure from port A is discharged through a directional control valve, the air pressure from port C pushes the back packing and moves the valve to port A. As a result, the air pressure from port C is quickly discharged through port B.
