What is a Solenoid Valve?
An electromagnetic actuator (solenoid) and a valve body make up a solenoid valve, which is an on/off electromechanically actuated valve. The valve actuator is the solenoid-plunger assembly, which opens and closes the valve. This actuator can be configured so that the plunger motion is limited to either opening or closing.
Types of Solenoid Valve Operations
The components of direct acting (direct operated) solenoid valves have a simple working principle. With no power, the plunger blocks the orifice with the valve seal for a normally closed valve. This closure is being forced by the arrival of a spring.
Solenoid Valve Components
All materials used in the construction of the valves are carefully selected according to the varying types of applications. Body material, seal material, and solenoid material are chosen to optimize functional reliability, fluid compatibility, service life and cost.
Circuit Functions of Solenoid Valves
Solenoid valves are used to close, open, dose, distribute or mix the flow of gas or liquid in a pipe. The specific purpose of a solenoid valve is expressed by its circuit function.

Physical Solenoid Principle
A solenoid is basically a device that is able to create a strong and uniform magnetic field on the inside and a very weak one on the outside.
A Solenoid used in a Practical Application
The mechanics of how a solenoid works are very simple. When electricity runs through the coil, located the inside of the actuator, it pushes a plunger that connects two terminals.
