READ MOREHow to connect the wires to the single-head solenoid reversing valve
The wire connection of the single-head solenoid directional valve needs to be operated according to its voltage type (DC or AC) and specific terminals. The following are detailed steps and precautions: 1. Prepare to confirm the voltage type before wiring. Direct current (DC) solenoid valve: It is necessary to distinguish the positive and negative poles (usually marked '+' and '-'). Reverse connection may cause non-operation or damage. AC solenoid valve: No need to distinguish polarity, live and neutral wires can be connected arbitrarily. Check the voltage value: Make sure the power supply voltage is consistent with the rated voltage of the solenoid valve (such as 24V DC, 220V AC, etc.). Identify the wiring terminal of the two-wire solenoid valve: usually the power wire (positive/live wire, negative/neutral wire), some with grounding terminal (yellow and green two-color wire). Three-wire solenoid valve: may include common terminal (COM), normally open terminal (NO), normally closed terminal (NC), which need to be connected according to the control logic. Solenoid valve with indicator light: The indicator light wire must be connected according to polarity, otherwise it will not light up but will not affect the function.

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
