The hydraulic control valve consists of main valve, solenoid valve, needle valve, ball valve, microfilter and pressure gauge.The remote control of valve opening and closing can be realized through solenoid valve.After installing additional device, the speed of opening and closing can be controlled.
The electric control hydraulic control valve USES the pilot valve to control the opening and closing of the valve, saving energy.Can replace other valve large electric device.
Electric control hydraulic control valve products are widely used in high-rise buildings, living areas and other water supply pipe network systems and urban water supply projects.
Electric control hydraulic control valve working principle.
When the valve is supplied from the inlet, the flow of water flows through the needle valve into the main valve control room. When the solenoid valve is opened, the water in the control room flows through the electromagnetic guide valve and the ball valve.Ball valve opening is greater than needle valve opening, main valve control room pressure is very low, main valve in full open state.
When the solenoid valve is closed, the water in the main valve control room cannot flow out, and the control room is raised to push the diaphragm to close the main valve.
