600X electric control valve is a solenoid valve as the guide valve of the hydraulic operated valve. Commonly used in water supply and drainage and industrial systems in the automatic control, control the response of accurate and fast, according to the electrical signal remote control open and close the pipeline system, remote operation. And can replace the gate valve and butterfly valve used for large electric operating system. Valve closing speed can be adjusted, stable and close without pressure fluctuations. The valve has the advantages of small volume, light weight, simple maintenance, convenient use, safety and reliability, and the electromagnetic valve can be used for alternating current 220V, or direct current electric 24V, and can be used in various occasions.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure,
1、作泄压阀:当泄压/持压导阀调整为泄压状态时,水通过针阀、主阀控制室、球阀A、泄压/持压导阀、球阀B流向出口,此时主阀处于开启状态。当进口压力超过泄压/持压导阀设定的安全值时,泄压导阀会自动开启,通过球阀C放出部分水,使管路泄压。当压力恢复到安全值时,泄压阀自动关闭。作泄压阀时,各球阀常开。
2、作持压阀:当泄压/持压导阀调整为持压状态时,只要主阀进口水压低于导阀设定值,导阀即关闭。主要控制室升压,主阀关闭。当主阀上游供水压力超过导阀设定压力时,持压导阀才能打开,控制室的水经球阀排至出口,控制室降压主阀开启,开始供水,即保持了上游水压。作持压阀用时,球阀C常闭或用丝堵换下。
