Solenoid Directional Control Valve 4WE6
TheSolenoid Directional Control Valve 4WE6is a direct-acting solenoid-operated directional spool valve, serving as a critical control component in hydraulic systems. Below is a detailed introduction to its specific features:
------
I. Working Principle
• The4WE6 solenoid directional control valveachieves the opening, stopping, and directional change of fluid pathways through electromagnetic actuation.
• When the solenoid is energized, electromagnetic force acts on the valve spool (or sliding valve), pushing it to the desired working position, thereby altering the fluid flow direction.
• When the solenoid is de-energized, the valve spool returns to its initial position under the action of a return spring, restoring the original fluid flow path.
------
II. Structural Features
• Wet Solenoid Design: The solenoid is fully enclosed and insulated internally, with the armature moving in oil. This reduces wear and impact, improves heat dissipation, and extends the reliability and service life of the valve's shifting and resetting operations.
• Plate-Type Connection: Utilizes a plate-type connection method, facilitating compatibility with various hydraulic systems and enabling easy adaptation to different brands of directional control valves.
• Sliding Valve Assembly: The internal sliding valve assembly includes a return spring to ensure automatic resetting of the valve spool when the solenoid is de-energized.
• Cast Inner Channel Process: The valve body employs a cast inner channel process, reducing pressure loss and enhancing flow capacity.
------
III. Performance Parameters
• Maximum Flow Capacity: Up to 80 L/min, meeting the demands of various hydraulic systems.
• Maximum Operating Pressure: Up to 350 bar (or varies by specific model), suitable for high-pressure hydraulic systems.
• Solenoid Type: Supports wet AC or DC solenoids, allowing selection based on actual requirements.
• Electrical Connection: Offers separate or centralized electrical connection types for convenient installation and maintenance.
• Sliding Valve Functions: Provides multiple standard sliding valve function configurations (e.g., 53 standard types) to meet diverse control needs.

IV. Functional Characteristics
• Manual Emergency Operation: Some models are equipped with manual emergency operation functionality, allowing manual pushing of the valve spool in emergencies to ensure safe system operation.
• Removable Coil: The coil is designed to be removable, enabling coil replacement without draining oil, significantly improving maintenance efficiency.
• Solenoid Rotation: The solenoid can be rotated 90 degrees, facilitating installation and layout and enhancing system flexibility.
• Fault Inspection Button: Optionally equipped with a fault inspection button for quick diagnosis and troubleshooting.

V. Application Fields
• The4WE6 solenoid directional control valveis widely used in various hydraulic systems, such as machine tools, metal processing and forming machinery, and automation equipment.
• It is suitable for applications requiring precise control of fluid flow direction, such as the extension and retraction of hydraulic cylinders and the rotation of hydraulic motors.
