When the valve from the inlet water, the water flow through the valve into the main valve control room, when the solenoid pilot valve is opened, control room of the water by the solenoid pilot valve, ball valve outflow. The valve opening is greater than the needle valve opening, the main valve control room pressure is very low, the main valve in the fully open state.
Â
When the solenoid valve is closed, the main valve control room of the water can not flow out, the control room to boost, and push the diaphragm off the main valve.
