4WREE10W75-2X/G24K31/F1V Rexroth Proportional Valve 75L/min

Model Number	R901496719 4WREE10W75-2X=G24K31/F1V

Product Description

Product Overview

The 4WREE10W75-2X/G24K31/F1V (related material number R901496719 and similar) is a Bosch Rexroth 4WREE series direct-operated proportional directional valve. Equipped with electrical position feedback and integrated on-board electronics (OBE), it precisely controls the direction and magnitude of flow. The spring-centered spool (symbol W, with A and B connected to T in neutral) delivers a rated flow of 75 L/min at Δp = 10 bar. Fully compliant with ISO 4401-05 mounting standards, the valve offers true interchangeability as a drop-in replacement for original Rexroth units without manifold or piping modifications. Every unit undergoes precision machining and 100% simulated duty-cycle testing to ensure high response sensitivity, low hysteresis, and stable proportional performance.

Key Technical Advantages

Integrated OBE with closed-loop position feedback – Built-in electronics and electrical position sensing deliver low hysteresis and high response sensitivity for precise proportional flow control.
Efficient direct-operated design – No pilot oil required; compact construction provides high flow capability at low pressure drop, ideal for medium-to-high flow high-precision applications.
True interchangeability and standard interfaces – Fully compliant with ISO 4401 NG10 mounting pattern, enabling direct drop-in replacement of original Rexroth valves and minimizing system modification costs.
Reliable spring centering and long service life – Spring-centered spool combined with precision manufacturing and 100% duty-cycle testing ensures stable long-term operation and high MTTF.

Application Areas

Ideal for injection molding machines, die-casting equipment, hydraulic presses, machine-tool feed systems, test stands, steel and metallurgical plants, and any medium-to-high flow industrial closed-loop hydraulic system requiring precise position, velocity, or force control.

Expert Maintenance Tips

Ensure manifold surface quality meets specifications and tighten mounting bolts to the correct torque; lock the electrical connector properly and verify protective earth; maintain fluid cleanliness at ISO 4406 20/18/15 or better; periodically check position feedback signals and amplifier parameters; confirm command-signal zero point before first power-up; during extended downtime, energize the valve periodically to keep the spool lubricated.
