The 4WRTE32E600L-4X/6EG24K31/A1M valve is manufactured by Bosch Rexroth for the 4WRTE Directional Control Valves series and is used to meter flow and shift actuator ports in hydraulic automation circuits. The nominal size 32 body handles a rated flow of 600 l/min at a 5 bar pressure drop, enabling high-volume control of large cylinders. A maximum operating pressure of 350 bar on ports P, A, and B supports heavy-duty systems without loss of accuracy. All service and tank ports share a 38 mm diameter, simplifying pipe selection and balancing velocities. The valve mounts on manifolds built to ISO 4401-10-09-0-05, so it can replace similar modules without re-machining. Internal pilot oil supply removes the need for separate pressure lines, while an external pilot oil return provides a dedicated drainage path to the reservoir. Reliable operation depends on oil cleanliness maintained to ISO 4406 class 18/16/13, protecting the precision spool edges from contamination.
Electronic actuation is driven by a ±10 V analog command, giving proportional spool positioning from standard motion controllers. The onboard electronics draw a 24 V DC supply and can reach 1.6 A, resulting in a maximum electrical demand of 72 VA that must be considered when sizing the power source. Connection is made through a single DIN EN 175201-804 plug coded K31, which streamlines field wiring. An integrated position sensor reports spool movement, enabling closed-loop monitoring by the control system. The external return port T may see pressures up to 250 bar without affecting performance, extending application range in back-pressurized circuits. An IP65 enclosure protects the electrical section against dust ingress and low-pressure water jets, allowing reliable duty outside enclosed cabinets.
