What is a solenoid valve? How does it work?
Solenoid valve is an industrial equipment controlled by electromagnetism, is used to control the basic components of fluid automation, belongs to the pneumatic actuator, and is not limited to hydraulic and pneumatic. The solenoid valve has a closed cavity with through holes at different locations, each hole is connected to a different oil pipe, the middle of the cavity is a piston, and the two sides are two electromagnets, which side of the magnet coil is energized the valve body will be attracted to which side, by controlling the movement of the valve body to open or close the different oil discharge holes. And the inlet hole is always open, the hydraulic oil will enter the different discharge pipes, and then through the pressure of the oil to push the piston of the cylinder, and the piston drives the piston rod, and the piston rod drives the mechanical device. This controls the mechanical movement by controlling the current flow of the solenoid.
