Product Description
4WE6 Series Direct-Operated Solenoid Directional Valves
Product Overview: The 4WE6 series is the industry standard for starting, stopping, and switching the direction of hydraulic fluid in industrial systems. As a direct-operated solenoid spool valve, it complies with ISO 4401-03 (NG6) mounting standards, offering exceptional interchangeability. Featuring wet-pin AC/DC solenoids, the armature operates within the oil, ensuring superior heat dissipation and damping. This significantly reduces mechanical shock and noise during switching, making the 4WE6 a reliable choice for precision machine tools, injection molding, and mobile machinery.
Featured models include: 4WE6D-50/AW220NZ5L, 4WE6D-50/AW220-50NZL, 4WE6H-50/AW220NZ5L, and optimized 12V/24V variants.
Key Technical Advantages:
High-Performance Wet-Pin Solenoids: The static-seal design eliminates external leakage at dynamic points. Coils are fully encapsulated with premium insulation for humidity resistance.
Versatile Control Voltages: Available in AW220 (AC 220V) for industrial grids and 12V/24V DC for mobile equipment and PLC control systems.
Low Pressure Drop & High Flow: Internally optimized flow channels ensure minimal pressure loss, resulting in lower system temperature and higher efficiency.
Z5L Standard Connection: Equipped with plug-in electrical connectors (indicator light options available), rated at IP65 for simplified field maintenance.
