4WEH25 Electro-Hydraulic Reversing Valve
The 4WEH25 electro-hydraulic reversing valve is a key control element in industrial hydraulic systems, with high precision, high reliability and flexible configuration options, suitable for a variety of complex working conditions. The following is a detailed introduction from the aspects of technical parameters, functional characteristics, application scenarios and selection suggestions:
1. Technical parameters
Diameter: 25mm (NG25), suitable for medium and large hydraulic systems.
Nominal pressure: up to 31.5MPa (some models support 35MPa).
Flow range: The flow can reach 1100L/min, meeting the needs of large flow.
Electrical parameters: Supports various voltages such as DC24V and AC220V, and the electromagnet has low power and less heat generation.
Operating temperature: -20℃ to +80℃, adapt to harsh environments.
2. Functional characteristics
The pilot control uses a solenoid valve as the pilot control element, and the main valve core is driven by electromagnetic force to achieve accurate reversal.
Optional wet AC or DC solenoids, with or without manual buttons, to meet different control needs.
The main valve structure The main valve core adopts a slide valve design, which enables valve position switching through hydraulic oil pressure.
Supports spring centering or hydraulic centering to ensure that the valve core automatically resets after power is off.
Additional features include optional commutation time regulators to optimize system response speed.
Optional main valve stroke regulator or terminal position indicator to accurately control the valve core displacement.
Supports extended functions such as prepressure valves, plug-in dampers, etc. to improve system stability.
III. Application scenarios
Industrial automation is used to control the action direction and speed of actuators such as hydraulic cylinders and hydraulic motors, and is widely used in CNC machine tools, injection molding machines, presses and other equipment.
Construction machinery realizes precise control of hydraulic systems in excavators, cranes and other equipment to improve equipment operation performance.
Metallurgy and energy are used for high-temperature and high-pressure working conditions such as ladle tilt and steam valve control to ensure stable operation of the system.
Environmental protection and chemical industry control the flow direction and flow of fluids in the fields of sewage treatment, petrochemicals, etc., and ensure the safety of the process flow.
4. Product Advantages
The high-reliability electromagnet is completely closed inside, reducing wear and impact and extending service life.
The valve core and valve body are made of high-strength materials, which are resistant to high pressure and corrosion.
High-precision control enables accurate reversal of hydraulic oil through the precise coordination between the solenoid valve and the main valve.
The valve core position monitoring function can be optionally used to provide real-time feedback on the valve core status.
Flexibility and compatibility support multiple electrical connection methods and are compatible with different control systems.
The oil port mounting surface complies with ISO 4401 standards, making it convenient for integration into existing hydraulic systems.
The solenoid coil is convenient to rotate 90°, and there is no need to open the pressure-resistant sealed cavity when replacing the coil.
Manual emergency operation device to ensure that the valve can still be switched when there is no magnet for power supply.
