Operation

2-Way Version - When pressure is applied to the PILOT port, the main ports (IN and OUT) are opened to allow flow through the valve. When the pilot pressure is released, a spring closes the main ports.

2-Way Vented Version - When Pilot Pressure is applied to the PILOT port, IN Port is open to the OUT Port; the VENT Port is closed. When pilot pressure is removed, the IN Port closes while the VENT Port opens to the OUT Port, relieving pressure within the valve and down stream piping. When used on a fuel gas system, the fuel intake manifold is vented causing quick shutdown of the engine.
