The Bosch Rexroth R901183072 (type 4WREQ6Q5-08-2X/V00-24PA63) is a genuine proportional directional valve with NG6, 8 l/min, 24 V DC. RendatSP supplies it new and original, ready to ship worldwide.
Rexroth proportional directional valves control both the direction and the speed of an actuator in proportion to an electrical command signal. They are found on injection moulding machines, presses, test benches and die-casting machines where smooth acceleration and repeatable positioning matter. Replacing a failed proportional valve with the exact same type code keeps the original spool characteristic and electronics, so the machine usually needs only a short parameter check instead of a full re-tune.

Rexroth type codes are configuration-specific: a different letter or number in any position gives a different material number. Always compare the full code with the nameplate of your original part.
Typical Applications

Frequently Asked Questions
Is the R901183072 a genuine Bosch Rexroth part?
Yes. RendatSP supplies the R901183072 as a new, original Bosch Rexroth part in factory packaging. We confirm the exact type code against your nameplate before shipping.
Do I need to re-tune the machine after replacing a proportional valve?
With the identical type code the spool characteristic and electronics stay the same, so usually only a short check of offsets and ramps in the machine control is required.
Can a proportional valve replace a standard on/off valve?
Not directly. A proportional valve needs an analogue or fieldbus command signal and suitable electronics. Send us your circuit details and we will advise.
What information do I need to order?
The full type code and the material number from the valve nameplate. Photos of the nameplate and connector help us confirm the exact match.
