YQ98006 Type Filter Piston Electromagnetic Control ValveDetailed product description：

The YQ98006 electromagnetic control valve consists of a main valve, an electromagnetic pilot valve, a needle valve, a ball valve, and a micro filter to form a hydraulic control connection system. Remote control of valve opening and closing can be achieved through electromagnetic pilot valves. When the valve supplies water from the inlet end, the water flows through the needle valve into the upper chamber control room of the main valve. When the solenoid valve is opened, the water in the control room flows out through the solenoid valve and ball valve. When the opening of the ball valve is greater than that of the needle valve, the pressure in the control room of the upper chamber of the main valve decreases, and the main valve is in a fully open state. When the solenoid valve is closed, the water in the control room of the upper chamber of the main valve cannot flow out, and the pressure in the control room increases, pushing the piston to close the main valve. This product uses a pilot valve to control the opening and closing of the valve, which reflects accurately and quickly. It adopts a three-way solenoid valve and is easy to maintain. Installed on pipelines of various water supply systems.
