|3/4/5 Port Solenoid Valves

What is the piping situation of VH series hand valves?

The VH series valve’s piping ports are as follows: 1 (P) = supply port, 2 (A) = A port, 3 (R) = exhaust port, and 4 (B) = B port. A silencer can be installed on the 3 (R) exhaust port.
Note 1) Do not apply pressure from any port other than the 1 (P) port. If supplied from another port, air will leak.
Note 2) This product cannot be used as a selector valve (selection between 2 types of inlet) or for negative pressure (vacuum). It cannot be used as a divider valve (1 inlet, 2 outlets, and a plugged exhaust port) either. Do not restrict the flow rate by plugging or mounting a speed controller to the exhaust port.
