 I. Overview 
 YQ98006 from the main valve solenoid control valve, solenoid pilot valve, needle valve, ball valve, micro-shaped filter composed of hydraulic control over the system. Can be achieved through the pilot valve solenoid valve to open and close the remote control. When the valve from the inlet water, the water flows through the needle valve chamber into the main control room, when the solenoid pilot valve opens, the control room to guide the water through the electromagnetic valve, ball valve outflow. Needle valve opening is greater than opening the main valve chamber control room pressure becomes low, the main valve is fully open state. When the solenoid pilot valve closed, the main valve on the water can not flow chamber of the control room, control room boost, push the piston off the main valve. This product is controlled by pilot valve to open and close the valve to reflect the accurate and quick, three-way solenoid valve with easy maintenance. Water supply system installed in various pipelines. The main valve part material as follows:
