What is the function of the solenoid valve

Solenoid valve is the basic equipment for automatic switching relying on electromagnetic force. Its main function is to control the automation of objects. It belongs to executive components. It is used to regulate medium direction, flow, speed and other parameters in industrial control system. It is widely used in various fields of production.

When using the solenoid valve, pay attention to its tightness and observe whether there is aging, damage and other phenomena. Once there is a problem, repair it in time to avoid affecting the normal use of the machine. In addition, the seal usually has hard seal and soft seal. When it works, you can close your ears to listen to the sound of air leakage, or test it with soapy water. If there is air leakage, bubbles will appear. If it is confirmed that there is no air leakage, you can change the seal.

Secondly, pay attention to the service environment of the equipment. If it is in places with large chemical reaction, it is necessary to select corrosion-resistant equipment, because different equipment has different characteristics, do not mix them, otherwise it will affect its service life. When installing the solenoid valve, it must be correct. Corresponding to the installation indicated by the arrow, the direction with the medium should be maintained all the time, and there should be no reverse differential pressure, so as not to fail to start normally.
