Description

There is a closed cavity in the solenoid valve, with through holes at different positions, 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 will be attracted to the valve body At the same time, different oil discharge holes are opened or closed by controlling the movement of the valve body, while the oil inlet holes are normally open.

The hydraulic oil will enter different oil discharge pipes, and then the piston of the oil cylinder will be pushed by the pressure of the oil, and the piston will drive the piston rod, and the piston rod will drive the mechanical device. In this way, the mechanical movement is controlled by controlling the current on and off of the electromagnet.

Hydraulic solenoid valve refers to the components used in hydraulic transmission to control the pressure, flow and direction of liquid. The one that controls the pressure is called the pressure control valve, the one that controls the flow is called the flow control valve, and the one that controls the opening, closing and flow direction is called the directional control valve.

Characteristic

1. External leakage is blocked, internal leakage is easy to control, and it is safe to use.
2. Simple system, easy maintenance and low price.
3. The action is fast, the power is small, and the shape is light.

4.Extend equipment life

5.High efficiency and long working life.
