What's a Solenoid Valve? A solenoid valve is an electrically operated valve that's mainly used to regulate the circulation of air or a liquid in pneumatic and hydraulic power methods. It is mostly configured to a spool or a poppet that is in flip related to a ferrous metal plunger that could be spring-centered or spring offset. The plunger itself moves inside a core tube of non-ferrous steel that in turn 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 assembly, which opens and closes the valve. This actuator will be configured in order that the plunger motion is limited to both 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 3 totally different ports: the inlet port that brings in a pressurized gas, the outlet port for خرید شیر برقی its exit, and a 3rd exhaust port for used air. It also 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 condition, the core spring, assisted by the fluid pressure, holds the valve seal on the valve seat to shut off the stream. When energized, the core and seal are pulled into the solenoid coil and the valve opens. The electro-magnetic power is higher than the mixed spring pressure and the static and dynamic pressure forces of the medium.
