Positioning Pilot Valve Model #X

This multi-purpose, direct acting, 3-Way positioning pilot valve 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".
