Solenoid valves include one-way valves, safety valves, directional control valves, etc., which play different roles in industrial control systems. Solenoid valves are industrial equipment controlled by electromagnetics, mainly used to control parameters such as the direction, flow rate, and speed of fluids. Its working principle is to control the opening and closing of the valve by energizing and de-energizing the electromagnet, thereby realizing the automatic control of the fluid.
There are various types of solenoid valves, the most common of which are multi-function solenoid valves and NASS solenoid valves. Multi-function solenoid valves combine the functions of pilot solenoid valves, manual valves, and throttle valves. The flow rate and the main valve switching time can be manually adjusted, and they are suitable for air, gas, steam, water and other media. NASS solenoid valves are widely used in large fluid control valves and pneumatic tools with their advanced pilot control technology.
When selecting, it is necessary to select according to pipeline parameters, fluid parameters, pressure parameters and environmental requirements. For example, the size of the solenoid valve should be determined according to the diameter specifications and interface methods of the pipeline; the appropriate material and structure should be selected according to the temperature, viscosity and pressure of the fluid; in addition, the working mode of the solenoid valve, such as normally closed or normally open, and whether explosion-proof, waterproof and other functions are required should also be considered.
