READ MOREWhat is the function of 4WE6 high-pressure solenoid reversing valve?
The 4WE6 high-pressure electromagnetic reversing valve is the core direction control component in the hydraulic system. Its core function is to realize the switching, on-off control and reversal function of liquid flow through electromagnet control, thereby driving hydraulic actuators (such as hydraulic cylinders and hydraulic motors) to complete precise actions. The following is a detailed description of its specific functions and technical characteristics: 1. The core function of flow direction switching and on-off control is to energize or de-energize the electromagnet to drive the valve core to move in the valve body and change the liquid flow path. For example: switching the liquid from the oil inlet (P port) to the working oil port (A port or B port), driving the hydraulic cylinder to extend or retract; blocking the oil flow (neutral function), keeping the hydraulic cylinder in a stationary or locked position. In a double-acting hydraulic cylinder, the reciprocating motion of the piston (such as telescopic, lifting, rotating, etc.) is achieved by alternately switching the energized state of the electromagnet. System safety protection: When the system pressure exceeds the set value, the electromagnetic reversing valve can automatically open the overflow channel to prevent

READ MORE4What are the characteristics of the WEH16 electro-hydraulic directional valve?
As a spool-type directional valve controlled by a solenoid valve as a pilot, the 4WEH16 electro-hydraulic directional valve has a series of significant characteristics. The following is a detailed introduction in five aspects: structure, performance, control method, additional devices and application areas: 1. Structural characteristics Plate connection: The 4WEH16 electro-hydraulic directional valve adopts a plate connection, and its connection dimensions comply with DIN24340A and ISO4401 standards, making it easy to install and replace. Core components: The valve is mainly composed of a main valve body, a main valve core, one or two return springs, and a pilot solenoid valve with one or two electromagnets. The main valve core is held in the middle position by spring force or hydraulic pressure, and the pilot solenoid valve controls the direction of the main valve. 2. Performance characteristics and high reliability: 4WEH16 electro-hydraulic directional valve has high reliability and can work stably under various harsh working conditions. Fast reversing response: The valve has fast reversing response and sensitive response, which can meet the needs of high-speed automated production lines.

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.
