What Is The Working Principle Of Solenoid Valve?
Mar 19, 2018

What is the Working principle of Solenoid valve?


Electromagnetic valve opening and closing is generated by electric current flows through the coil to control electromagnetic suction, the current is controlled by various relays, controllers, liquid-level controller and the demand sign of kinds of relay, controller and manual switch.


The solenoid valve is divided in direct and indirect opening and closing by it's opening method.

Direct open-close type solenoid valve is directly by controlling the coil current, to control in electromagnetic heart of electromagnetic attraction, and the electric magnetic head of electric magnetic core directly go to the opening and closing of valve port, suitable for small diameter pipeline.


Indirect open-close type solenoid valve is by controlling the coil current, to control in electromagnetic heart of electromagnetic attraction, electric magnetic core is controlling the piston valve group, by the mouth opening and closing valve, piston valve group is suitable for large diameter pipeline.
