Working Principle
Through pressure transmission via the hydraulic conduit, the main valve slide plate (valve disc) mimics the action of the pilot valve. When the electrical signal is an opening command, the solenoid valve opens to release the pressure water above the diaphragm, and the main valve opens. When the electrical signal is a closing command, the solenoid pilot valve closes, and the upstream pressure acts on the top of the diaphragm to close the main valve.
