Category: WATER CONTROL VALVE
working principle:
When the valve supplies water from the inlet end, the water flows through the needle valve and enters the main valve control room. When the solenoid pilot valve opens, the water in the control room flows out through the solenoid pilot valve and the ball valve. The opening of the ball valve is greater than the opening of the needle valve, the pressure in the main valve control chamber is very low, and the main valve is in a fully open state. When the solenoid pilot valve is closed, the water in the main valve control chamber cannot flow out, and the pressure in the control chamber increases, pushing the diaphragm to close the main valve.
