Rexroth Type 4WE6 Valve | 4WE6E 4WE6D | 24V DC 220V AC Solenoid Valve | NG6

4WE6 Series Industrial Solenoid Directional Valves (Size 6 / NG6)

Product Overview: The 4WE6 Series is a direct-operated directional spool valve actuated by solenoids, serving as a cornerstone for hydraulic control systems worldwide. As the industry standard for Size 6 (NG6), these valves are celebrated for their high switching power limits, low pressure-drop architecture, and exceptional operational reliability. Whether operating on 220V AC industrial grids or 24V DC mobile power sources, the 4WE6 provides precise fluid direction control with pressure capabilities up to 315-350 Bar.

This selection features high-performance configurations: the 3-position 4WE6E (closed center) and the 2-position 4WE6D (with manual override).

Key Technical Advantages:

• High-Efficiency Solenoid Drive: Features wet-pin solenoids where the armature moves in oil, providing superior cooling and self-lubrication for extended service life and reduced shifting impact.

• Global Voltage Compatibility: Available in CW220 (220V AC) and G24/ED24 (24V DC) options, making them compatible with various industrial grids and PLC control systems.

• Optimized Flow Channels: Precision-cast internal galleries minimize pressure drop even at high flow rates, enhancing energy efficiency and reducing heat generation.

• Manual Override Feature: Equipped with integrated manual override buttons (N9), allowing for emergency switching and system troubleshooting during power outages or commissioning.
