This high sensitivity, 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 has a tolerance between opening and closing functions of either 0.5m or 1m.
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”
