READ MOREHow to use 4WE10 high-pressure solenoid reversing valve
1. Basic structure and working principle 4WE10 high-pressure solenoid directional valve is mainly composed of valve body, electromagnet, control valve core and return spring. Its working principle is based on the action of electromagnetic force: In the power-off state: the control valve core is held in the intermediate position or initial position by the return spring (depending on the functional type of the valve, such as the 'O' type functional valve core is in the middle closed state). At this time, the oil inlet chamber is not connected with the working oil chamber and the oil return chamber, and the system is in a static state. Energized state: When the electromagnet is energized, a magnetic field is generated to attract the control valve core to move to the required end position. According to different combinations of electromagnet energization, the following functions can be achieved: Single electromagnet energization: the control valve core moves to one side so that the oil inlet chamber is connected to a certain working oil chamber, and the other working oil chamber is connected to the oil return chamber, thereby driving the hydraulic actuator (such as a hydraulic cylinder or hydraulic motor) to move in one direction. The other electromagnet is energized: the control valve core moves in the reverse direction and changes the flow rate of the working oil chamber.

READ MOREHow to use ZDB10V stacked relief valve
The usage of ZDB10V stacked relief valve is as follows: Preparation before installation: Make sure the system is clean: The system needs to be thoroughly cleaned before installation to prevent impurities from entering the valve and affecting performance. Make sure the mounting surface and oil port are clean: there should be no contaminants on the mounting surface and oil port to ensure tightness. Choose the installation location: The valve adopts a stacked design and can be installed directly on the bottom plate of the reversing valve or other hydraulic valves, saving space and simplifying the pipeline. Installation steps: Correct stacking installation: stack the valve in the correct direction on the valve block or base plate interface that complies with ISO 4401 standards. Tighten the mounting screws evenly: Tighten the mounting screws evenly using the specified torque to ensure a secure connection. Pay attention to the direction of the oil port: ensure that the oil inlet (P) and oil return port (T) are correctly connected to avoid oil circuit errors. Pressure adjustment: Use the adjusting screw to set the pressure: Set the required maximum working pressure of the system by rotating the adjusting screw on the valve. Recommended pressure gauge calibration: Adjustment

READ MOREPrecautions for using 4WE6 high-pressure solenoid directional valve
Precautions for using the 4WE6 high-pressure solenoid reversing valve are as follows: Preparation before installation: Model verification: Before installation, the model and specifications of the solenoid valve need to be carefully checked to ensure that they are consistent with the system design requirements, including working pressure, flow, voltage and other parameters. Appearance inspection: Check whether there is any damage to the appearance of the solenoid valve, such as cracked shell, damaged coil, etc., to ensure that the solenoid valve is intact. Pipe cleaning: Clean the inside of the pipe connecting the solenoid valve to remove impurities, rust, welding slag and other foreign matter to prevent impurities from entering the solenoid valve and causing the valve core to jam or seal loosely. Installation location selection: Choose a dry, well-ventilated location that is convenient for operation and maintenance to install the solenoid valve. Avoid installing it in places with strong vibration, impact, or close to heat sources. Precautions during the installation process: Installation direction: Install strictly according to the fluid flow direction marked on the solenoid valve shell, ensuring that the medium flows in from the inlet end and flows out from the outlet end. Wrong installation direction may cause the solenoid valve to fail.
