This multi purpose, direct acting 3-way positioning pilot Valve is actuated by a pressure responsive diaphragm, which seeks to reach equilibrium between hydraulic and set spring forces. The pilot directs flow and pressure between its ports:
- When sensed pressure is above set point, it connects port “0” to “3”.
- When sensed pressure is equal to set point, it blocks connections between all ports.
- When sensed pressure is below set point, it connects port “3” with “2”.
Relevant pressure is continuously sensed through port “1”.
