Hydraulic Electric Control Valve
Introduction:
The electric control valve is a hydraulic control nozzle system composed of main valve, electromagnetic pilot valve, needle valve, ball valve, micro filter and pressure gauge. The opening and closing of the valve can be remotely controlled through the electromagnetic pilot valve. After adding additional devices, the opening and closing speed can be controlled.
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 electromagnetic pilot valve is opened, the water in the control room flows out through the electromagnetic pilot valve and ball valve. The opening of the ball valve is larger than that of the needle valve. The pressure in the control room of the main valve is very low, and the main valve is fully open. When the solenoid pilot valve is closed, the water in the control room of the main valve cannot flow out. The control room boosts the pressure and pushes the diaphragm to close the main valve.
