Williams 111199 WM68A Three-Way Directional Relay Valve

The WM68A is a three-way directional relay with a 300 SCFM flow capacity. A control signal equal to 15-20% of supply pressure is required to open this normally closed valve. As illustrated in the schematic, the WM68A is used to speed response of large capacity pneumatic devices. A small control valve can deliver a sufficient signal to open or close the WM68A and move a large volume of air to or from the downstream actuator very rapidly.
