The 4WRREH6VB40L-1X/G24KO/B5M valve belongs to the 4WRE Proportional Directional Valves series manufactured by Bosch Rexroth for precise hydraulic automation tasks. It uses a V-type 4/3-way spool to direct flow in closed-center circuits, while its linear flow characteristic allows predictable adjustment across the control range. A nominal flow of 40 L/min at a 70 bar pressure drop supports medium-size actuator groups. Installation follows the ISO 4401-03-02-0-94 mounting pattern so it fits standard subplates. The unit tolerates 315 bar on the P, A, and B ports and up to 100 bar on the T port, making it suitable for high-pressure systems with elevated tank back-pressure. Overall weight is 2.5 kg, which simplifies handling during manifold assembly, and NBR seals are used to maintain compatibility with common mineral oils.
A ±10 V command input interfaces directly with analog motion controllers, and a 24 V DC supply powers the internal electronics. Electrical connection is achieved through an 11P+PE plug built to DIN 43563-AM6, providing secure wiring in industrial cabinets. The valve achieves a full-stroke response in 5 ms so it can follow fast positioning commands, and hysteresis is limited to 0.2% to improve repeatability in closed-loop circuits. An IP65 protection class permits installation in environments exposed to dust and low-pressure water jets. Power consumption peaks at 30 VA, easing load calculations for machine power supplies, and the permissible differential pressure across the spool is capped at 250 bar to protect internal components during transients.
