Rexroth 4WE6 Series Directional Solenoid Valves (NG6)

Product Overview:

The 4WE6 series is the most iconic directional control valve in industrial hydraulics, renowned for its exceptional reliability, high power density, and extended service life. Driven by wet-pin solenoids, it supports a wide range of spool functions (including D, G, H, J) to precisely manage the start, stop, and direction of fluid flow. Whether featuring the B10 integrated orifice or the classic 6X design series, the 4WE6 ensures stable control performance under pressures up to 350 bar.

Featured Material Numbers and Models:

• R900915069: Model 4WE6D6X/EG24N9K4/B10

• R900548271: Model 4WE6-6X/EG24N9K4/B10 (Universal Series)

Key Technical Advantages:

• High-Response Wet-Pin Solenoids: Armatures operate within the fluid for superior heat dissipation and damping, minimizing hydraulic shock and supporting stable DC 24V (EG24) operation.

• B10 Integrated Orifice Technology: The B10 suffix indicates a $\phi 1.0mm$ orifice integrated into the P-port, effectively preventing pressure surges during switching to protect actuators.

• Versatile Spool Functions:

  • 4WE6D: 2-position 4-way, dual solenoid, providing excellent switching precision.

  • 4WE6G/H/J: 3-position 4-way, covering logics from all-ports-blocked to all-ports-open centers.

• Global Standard Mounting: Complies with ISO 4401-03 (NG6) interfaces, allowing seamless replacement across global hydraulic power units.
