The hydraulic solenoid valve group is a device that combines the solenoid valve with the hydraulic system. It consists of solenoid valve, hydraulic valve, hydraulic oil tank, hydraulic pump, etc. The hydraulic solenoid valve group adjusts the flow direction, flow rate, pressure and other parameters of the hydraulic oil flow in the hydraulic system by controlling the switching status of the solenoid valve. Hydraulic solenoid valve groups are usually used in hydraulic control systems in industrial production, such as machine tools, metallurgical equipment, excavators, cranes, etc. It can realize automatic control of hydraulic system and improve production efficiency and safety. The working principle of the hydraulic solenoid valve group is to control the switching state of the valve core through the magnetic force generated by the electromagnet of the solenoid valve. When the solenoid valve is powered on, the magn…
