When the valve is fed water from the inlet end,the water flows through the needle valve into the main valve control room.When theelectromagnetic pilot valve is opened,the water in the control room flows out through the electromagnetic pilot valve and ball valve.The bal valve opening is greater than the needle valve opening,the pressure in the main valve control room is very low,and the mainvalve is in full open state.When the solenoid pilot valve is closed,the water in the main valve control room cannot flow out,and thecontrol room increases the pressure and pushes the diaphragm to close the main valve.
