READ MORECan the superimposed hydraulic control check valve be adjusted?
The superimposed hydraulic control check valve itself does not have the active adjustment function of flow or pressure, but it can indirectly achieve the adjustment effect through system design. Its core function is to control the unidirectional flow of oil and allow reverse flow under certain conditions, rather than directly adjusting flow or pressure parameters. The following is a specific analysis: The core function of the superimposed hydraulic control check valve is one-way cut-off: ensuring that oil can only flow in one direction, and is blocked in the opposite direction to avoid reverse flow or backflow. Hydraulic control opening: By introducing external control oil pressure, the reverse cutoff can be actively opened to allow reverse flow of oil. How to realize the adjustment function Although the superimposed hydraulic control check valve itself does not have the adjustment function, it can indirectly achieve the adjustment effect in the following ways: Use in combination with a regulating valve: In the hydraulic system, the superimposed hydraulic control check valve can be used in combination with other regulating valves (such as relief valves, throttle valves, etc.) to indirectly affect the work of the superimposed hydraulic control check valve by adjusting the parameters of other valves.

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.
