Excavator loader accessories PC200-8 Relief valve 723-40-91500

The working principle of the solenoid valve is: Solenoid valve has a closed chamber, open a hole in different positions, each hole is connected to a different tubing, the middle of the cavity is a piston, two sides are two electromagnets, which side of the magnet coil energized valve body will be attracted to which side, by controlling the movement of the valve body to open or close different oil discharge holes, and the oil inlet hole is usually open, hydraulic oil will enter a different oil discharge pipe, Then through the pressure of the oil to push the piston of the cylinder, the piston in turn drives the piston rod, the piston rod drives the mechanical device. In this way, mechanical motion is controlled by controlling the current of the electromagnet.
2, electromagnetic valve (Electromagneticvalve) is an industrial equipment controlled by electromagnetic, is used to control the basic components of automation fluid, belongs to the actuator, is not limited to hydraulic, pneumatic. Used in industrial control systems to adjust the direction of media, flow, speed and other parameters. The solenoid valve can be combined with different circuits to achieve the desired control, and the precision and flexibility of the control 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 are check valves, safety valves, direction control valves, speed regulating valves and so on.
