Solenoid Valve

Parameters of Solenoid Valve

Solenoid valves can be widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical, surface treatment, as well as bathrooms, cafeterias, air conditioning. It is mainly used for gas and liquid media.

Solenoid Valve

Description

Introduction of Solenoid Valve 

Steam (liquid) solenoid valve is an actuator for an industrial process automation control system, which can open or close automatically after receiving an electric signal to realize the on-off control of the fluid medium in the pipeline.

This series of solenoid valves can be widely used in textile, printing, chemical, plastic, rubber, pharmaceutical, food, building materials, machinery, electrical, surface treatment, and other production and scientific research departments, as well as bathrooms, cafeterias, air conditioning, and other people’s daily life. JC  series solenoid valve is mainly used for gas media such as air, steam, and coal gas and liquid media such as tap water, distilled water, frozen brine, and electroplating waste liquid, and also for oil with viscosity less than 4°E.

Working Principle of  Solenoid Valve 

the solenoid valve can be divided into normally open and normally closed according to the difference of presenting open or closed when energized. The working principle of the normally closed solenoid valve is: when no electrical signal is received, the solenoid valve is closed. When the solenoid coil is connected to the electrical signal, it will produce the corresponding magnetic field, under the action of electromagnetic force dynamic iron core and static iron core suction, dynamic iron core down, drive the valve stem to overcome the spring force down, the valve open. When the solenoid coil cut off the electrical signal, the magnetic field generated by the energized disappears, the electromagnetic force disappears, the dynamic core, valve stem, the valve will be in the spring force upward, so that the valve seals pressed on the valve seat to achieve a sealed state, the valve closed.

The working principle of the normally open solenoid valve is: when the electric signal is not connected, the solenoid valve is open. After the solenoid coil is connected to the electrical signal, it will generate the corresponding magnetic field, under the action of the electromagnetic force, the dynamic iron core and static iron core suction, the dynamic iron core upward, driving the valve stem, valve flap to overcome the spring force to move up, so that the valve seal is pressed on the valve seat to achieve sealing, the valve closed. When the solenoid coil cut off the electrical signal, the magnetic field generated by the energized disappears, the electromagnetic force disappears, the moving iron core, valve stem, valve flap moves under the action of the spring force, the sealing surface will be separated from the valve seat, the valve opens.
