Solenoid valve‍

Solenoid valve is electromagnetic control of industrial equipment. They are the basic components that control the fluid. They are actuators and are not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valve can be used with different circuits can be used to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play different roles in the control system. The most common are check valves, safety valves, directional control valves, speed control valves and so on.

Working principle

Solenoid valve has a closed chamber, open a through hole in different positions, each hole is connected to different tubing, the middle of the chamber is a piston, two sides are two electromagnets, which side of the magnet coil energized valve body will be attracted to which side, by controlling the movement of the valve body to open or close different oil holes, and the oil inlet hole is often open, hydraulic oil will enter a different oil discharge pipe, Then the pressure of the oil pushes the piston of the cylinder, which in turn drives the piston rod, which drives the mechanism. In this way the mechanical motion is controlled by controlling the current break of the electromagnet.

Installation instructions

1. When installing, please note that the arrow on the valve body should be consistent with the flow direction of the medium. Do not install it in a direct dripping or splashing area. Solenoid valve should be installed vertically upward;

2. The solenoid valve shall ensure the normal operation of 15% power supply within the fluctuation range of rated voltage -10%;

3. After the solenoid valve is installed, ensure that there is no reverse pressure difference in the pipeline. Need to preheat several times to make it suitable for use after preheating;

4. Clean the solenoid valve thoroughly before installation. The passing medium shall be free of impurities. Install the filter in front of the valve;

5. When the solenoid valve fails or is cleaned, a bypass device should be installed to ensure continued operation of the system.
