I. Overview 
 J145X electric remote control valve from the main 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 off the main valve diaphragm. This product is controlled by pilot valve to open and close the valve, the reaction quickly and accurately, three-way solenoid valve with easy maintenance. Water supply system installed in various pipelines. The main material valve parts as follows: 

 Part Name Material 
 Body, bonnet cast iron, cast steel, stainless steel 
 Bronze seat, stainless steel 
 Valve carbon steel, stainless steel + nitrile rubber 
 Qinggang aluminum stem, chrome stainless steel 
 Nitrile rubber diaphragm 
 Diaphragm plate carbon steel, stainless steel 
 Stainless steel spring 

 Second, characteristics 
 1, accurate and rapid control response. 
 2, the closing speed is adjustable. Valve does not produce a smooth closure of the pressure fluctuations. 
 3, three-way solenoid valve with easy maintenance.
