【Normally closed solenoid valve】Solenoid valve is an actuator for industrial process automation control systems. The device can be turned on or off automatically after receiving the electronic control signal to perform on/off control or flow regulation of the fluid medium in the pipeline. For use with lines in water, air, oil and low viscosity non-corrosive fluid applications. 【 Installation method】The direction of water flow is marked on the valve body. If installed in reverse, the solenoid valve will not work properly. There are two wires to be connected, one on the phase, the other on the neutral. One wire on the phase the other on the neutral regardless of the direction (be careful, it's 220 volts). The solenoid valve can be used for cold water and hot water up to 80 degrees. 【Horizontal installation】This solenoid valve is designed to be installed horizontally indoors in a dry environment. If used outdoors, the coil part should be well protected from water. Solenoid valves can be
