FAQ

What is the significance of the ‘J62’ spool type in this 4WE 6 valve?

The ‘J62’ designation refers to the specific spool configuration. It is a 3-position, spring-centered spool where in the neutral position, ports P, A, and B are connected to the tank (T), providing a float or circulation path for the fluid. This is often used to unload the pump when the actuator is not moving.

Can the 230V AC solenoids (R900071030) be replaced with a different voltage, for example 24V DC?

Yes, the solenoids on Rexroth 4WE 6 valves are generally interchangeable. You can replace the existing 230V AC coils with compatible 24V DC coils (e.g., model EW24N9K4) as long as the replacement coil is designed for the same valve series. However, ensure your control system can provide the correct DC voltage and current.

What type of hydraulic fluid is compatible with this valve’s standard seals?

The standard version of this valve typically comes with NBR (Nitrile) seals. These are compatible with common hydraulic fluids based on mineral oil (HL, HLP) according to DIN 51524. For use with synthetic fluids or at extreme temperatures, you should verify if special seals (e.g., FKM/Viton) are required.
