X – Positioning pilot 3 way


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”.
