4WRPE6EA18SJ-2X/G24K0/A1M

The 4WRPE6EA18SJ-2X/G24K0/A1M valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series. It meters hydraulic flow in closed-loop motion applications where proportional control is required. The nominal size is 6 (NG6), so it fits manifolds designed for small flow paths. An ISO 4401-03-02-0-94 mounting pattern allows direct installation on standardized subplates for compact circuit layouts. With a nominal flow of 18 l/min at a 5 bar differential, it supplies actuators that call for moderate volume without excessive pressure loss. The unit withstands working pressures up to 315 bar at ports P, A, and B, while the tank port tolerates 200 bar, providing a safe margin for return lines in high-duty cycles. Valve electronics operate from a 24 V DC supply, and maximum power consumption is limited to 40 VA to simplify power budgeting inside control cabinets. The command signal range of ±10 V (interface A1) accepts common analog outputs from motion controllers to set spool position. A 20 ms response time for a full-scale input step supports rapid load changes, and maximum hysteresis of 0.3 % keeps position deviation low during fine adjustments.

An IP65 degree of protection shields internal coils and electronics against dust ingress and low-pressure water jets, allowing placement next to machinery where fluid spray is present. Connection is handled through a 6P+PE plug complying with DIN 43563, so power, command, and feedback lines join through a single keyed connector for quick service swaps. The spool and lands rely on hydraulic oil meeting ISO 4406 class 18/16/13 cleanliness to maintain repeatable metering and avoid wear. Leakage per edge is limited to 80 cm³/min at a 100 bar differential, reducing heat generation and improving volumetric efficiency in standby conditions. An NBR seal package resists standard mineral oils and supports the stated pressure ratings without extrusion. The assembled mass of 3.9 kg keeps the manifold weight manageable and permits mounting on small machine plates or mobile frames. Together these parameters define the operational envelope of the valve and ensure consistent proportional control throughout its service life.
