FAQ

Question?

What is the significance of the "E" spool type in this 4WE 6 E62 valve?

The "E" spool is a spring-centered, 3-position configuration. In its neutral (center) position, it blocks all four ports (P, T, A, and B). This is a 'closed-center' type, which locks the actuator (e.g., a hydraulic cylinder) in place when the solenoids are de-energized.

Can I use a different voltage solenoid coil with this valve body?

Yes, the solenoid coils on Rexroth 4WE 6 valves are generally interchangeable. You can replace the existing 230V AC coils (Part no. R900071030) with others of the same physical size but different voltages (e.g., 24V DC), provided you use the correct corresponding electrical connector. Always verify compatibility with the Rexroth datasheet.

What are the mounting requirements for this NG6 valve?

This valve conforms to the NG6 (CETOP 3 / ISO 4401-03) mounting pattern. It requires a flat, machined subplate or manifold block with the corresponding port pattern. It should be secured with four M5 bolts, tightened to the manufacturer's specified torque to ensure a proper seal.
