E320 Excavator Electric Parts 4I-5674 Solenoid For Hydraulic Pump

Solenoid Valve Information:

A Solenoid valve is an automatic basic component used to control the direction of the fluid, which belongs to the actuator; it is usually used on mechanical control and industrial valves to control the direction of the medium, so as to control the valve switch.
The working principle of the solenoid valve:
There is a closed cavity in the solenoid valve, and there are through holes in different positions. Each hole leads to a different oil pipe. There is a valve in the middle of the cavity, and two electromagnets on both sides. To which side, the movement of the control valve body is used to block or leak different oil discharge holes, and the oil inlet hole is normally open, and the hydraulic oil will enter different oil discharge pipes, and then push the oil cylinder through the pressure of the oil. The piston drives the piston rod, and the piston rod drives the mechanical device to move. In this way, the mechanical movement is controlled by controlling the electric current of the electromagnet.
A Solenoid valve is industrial equipment controlled by electromagnetic, which is used in industrial control systems to adjust the direction, flow, speed, and other parameters of the medium. The Solenoid valve is controlled by electromagnetic effect, and the main control method is controlled by a relay. In this way, the solenoid valve can cooperate with different circuits to achieve the expected control, and the control accuracy and flexibility can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the control system. The most commonly used ones are check valves, safety valves, directional control valves, and speed-regulating valves.
The solenoid valve of the excavator is an automatic basic component used to control the fluid of the excavator. It belongs to the actuator and is not limited to hydraulic and pneumatic. It is used to adjust the direction, flow, speed, and other parameters of the medium in the industrial control system.
