Features of Youyan solenoid valve

2022-08-24 13:46:12

YUKEN solenoid valve is an automatic basic element used to control the direction of fluid, belonging to the actuator; It is usually used for mechanical control and industrial valves to control the medium, so as to control the valve switch.

working principle

The solenoid valve has a closed cavity. There are through holes in different positions. Each hole leads to different oil pipes. There is a valve in the middle of the cavity, and two electromagnets are on both sides. The valve body will be attracted to which side when the magnet coil is energized. The valve body will block or leak out different oil drain holes by controlling the movement of the valve body. The oil inlet hole is normally open, and the hydraulic oil will enter different oil drain pipes, and then push the piston of the oil cylinder through the oil pressure, The piston drives the piston rod, which drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet.

Direct acting solenoid valve

Principle: When energized, the solenoid coil generates electromagnetic force to lift the closing piece from the valve seat and open the valve; When the power is cut off, the electromagnetic force disappears, the spring presses the closing element on the valve seat, and the valve closes.

Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm
