4WEH32 Electro-Hydraulic Reversing Valve
4WEH32 electro-hydraulic reversing valve is the core control element in industrial hydraulic systems. With its high precision, high reliability and flexible configuration options, it is widely used in 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: 32mm (NG32), suitable for large hydraulic systems.
Nominal pressure: up to 35MPa, meeting the needs of high-pressure working conditions.
Flow range: The flow rate can reach 1100L/min, adapting to large-flow hydraulic circuits.
Electrical parameters: Supports various voltages such as DC24V and AC220V. The solenoid has low power and less heat generation, and is suitable for frequent start and stop operations.
Operating temperature: -30℃ 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.
The pilot control valve can be selected as a wet AC or DC solenoid 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.
