What is a Solenoid Valve? A solenoid valve is an electrically operated valve that is mainly used to regulate the movement of air or a liquid in pneumatic and hydraulic power programs. It is generally configured to a spool or a poppet that is in flip connected to a ferrous metallic plunger that could be spring-centered or سلونوئید ولو spring offset. The plunger itself moves inside a core tube of non-ferrous steel that in flip is surrounded by a coil comprised comprising of electrical windings. 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 meeting, which opens and closes the valve. This actuator could be configured in order that the plunger motion is proscribed to either opening or closing. Because there is no such thing as a intermediate or in-between position, a solenoid can not throttle flow.

This valve has three completely different ports: the inlet port that brings in a pressurized fuel, the outlet port for its exit, and a third exhaust port for used air. It additionally has two states, open and closed. Within the relaxed state, the inlet connects to the exit port. Upon closing, the outlet changes the connection to align with the exit port.

Two-manner valves are shut-off valves with one inlet port and one outlet port (Fig. 1). In the de-energized situation, the core spring, assisted by the fluid strain, holds the valve seal on the valve seat to shut off the flow. When energized, the core and seal are pulled into the solenoid coil and the valve opens. The electro-magnetic pressure is larger than the combined spring drive and the static and dynamic pressure forces of the medium.
