Positioning Pilot Valve Model X

This multi-purpose, direct acting, 3-Way positioning pilot is actuated by a pressure responsive diaphragm, which tends to reach equilibrium with the set spring force. The pilot directs flow and pressure between its ports:

•  When sensed pressure is above set point, it connects port C to 0.

•  When sensed pressure is equal to set point, it blocks connections between all ports.

•  When sensed pressure is below set point, it connects port C with A and Z. An integral needle valve restricts flow through port Z.
