The electromagnetic switching valve generally refers to the solenoid valve.The electromagnetic valve is an industrial equipment controlled by electromagnetic control. It is an automated basic element used to control the fluid. It belongs to a actuator and is not limited to hydraulic and pneumatic.Used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system.The solenoid valve can cooperate with different circuits to achieve the expected control, and the accuracy and flexibility of the control can be guaranteed.
The role of the electromagnetic direction valve
1. The solenoid valve is a switch between the liquid and the gas pipeline. It can control the conversion between the liquid and the gas. The solenoid valve is controlled by two DOs.So use the control of small pipes under normal circumstances.2. Because the circulation coefficient of the solenoid valve is relatively small under certain circumstances, the pressure difference between its work is not much different.For example, the electromagnetic valve circulation coefficient of 25 -caliber is much smaller than the electric ball valve with a diameter of 15.In other words, the driving force of the solenoid valve mainly depends on the electromagnetic coil. Therefore, the solenoid valve can achieve the two functions of opening and the turnover. This is why the liquid and gas conversion can be used at will in general.3. We know that the electromagnetic valve is driven by coils to generate power, which can make the action time shorter during the switch, and it is also very short in the transition of the steam -liquid phase, which can effectively reduce leakage and fluid medium mixing.

Principles of electromagnetic directional valve
The solenoid valve is a basic element used to control the fluid. The working principle of the solenoid valve is divided into the working principle of ordinary solenoid valve, the working principle of the direct -motion solenoid valve, the principle of distributed direct -motion solenoid valve, and the working principle of the pilot solenoid valve.There is a closed cavity in the solenoid valve. There are pores in different locations. Each hole is directed at different oil pipes. The middle of the cavity is a valve. On both sides, there are two electromagnets.Where to attract, live or leak different oil exhaust holes by controlling the movement of the valve body, and the oil inlet hole is often opened, and the hydraulic oil will enter different oil exhaust pipes, and then promote the oil through the pressure of the oil to promote the oil through the pressureIn the piston, the Pistons drive the piston rod, and the piston rod drives the mechanical device movement.In this way, the mechanical movement is controlled by controlling the current of the electromagnet.
