|3/4/5 Port Solenoid Valves

What is the flow path of VH series hand valves?

The flow path depends on the selected VH function: there are 2-position valves and 3-position valves.
The 2-position valve is a 2-stream hand valve that alternately supplies and exhausts air.
The 3-position closed center valve features a neutral position in which both the A and B ports are sealed (with air leakage) in addition to the 2 other positions.
The 3-position exhaust center valve features a neutral position in which air is exhausted from both the A and B ports in addition to the 2 other positions.
Turn the knob 90 degrees to change positions for the 2-position valve and 45 degrees for the 3-position valve. Refer to the following JIS symbols for details on the flow path, the direction of the knob, and the flow direction.
