4WEH16 Electro-Hydraulic Reversing Valve
4WEH16 electro-hydraulic reversing valve is a high-performance directional control valve widely used in industrial hydraulic systems. The following is a detailed introduction from the aspects of technical parameters, functional characteristics, application scenarios and advantages:
1. Technical parameters
Diameter: 16mm (NG16), suitable for medium and large hydraulic systems.
Nominal pressure: up to 31.5MPa (some models support 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, AC220V;
The electromagnet has low power and low heat generation, and adapts to frequent start and stop operations.
Operating temperature: -20℃ to +80℃, adapt to harsh environments.
2. Functional characteristics
Pilot control: Use a solenoid valve as the pilot control element to drive the main valve core action through 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.
Main valve structure: The main valve core adopts a slide valve design, and valve position switching is achieved through hydraulic oil pressure;
Supports spring centering or hydraulic centering to ensure that the valve core automatically resets after power is off.
Additional functions: optional commutation time regulator 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: used to control the action direction and speed of actuators such as hydraulic cylinders and hydraulic motors. It is widely used in CNC machine tools, injection molding machines, presses and other equipment.
Construction machinery: In excavators, cranes and other equipment, precise control of hydraulic systems is achieved to improve equipment operation performance.
Metallurgy and Energy: 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: In the fields of sewage treatment, petrochemical industry, control the flow direction and flow of fluids to ensure the safety of the process flow.
4. Product Advantages
High reliability: Wet electromagnet design is adopted, the 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, and adapt to harsh working conditions.
High-precision control: Through the precise coordination between the solenoid valve and the main valve, accurate reversal of hydraulic oil is achieved to meet the needs of high-precision control;
It can be equipped with a valve core position monitoring function, and real-time feedback of the valve core status to improve system safety.
Flexibility and compatibility: Supports multiple electrical connection methods (single or central connection), compatible with different control systems;
The oil port mounting surface complies with ISO 4401 standards, making it convenient for integration into existing hydraulic systems.
Convenient maintenance: the solenoid coil can rotate 90°, and there is no need to open the pressure-resistant sealed cavity when replacing the coil, simplifying the maintenance process;
Manual emergency operation device to ensure that the valve can still be switched when there is no magnet for power supply.
