The 4WRKE10W8-100L-3X/6EG24TK31/A1D3M valve belongs to the 4WRKE Directional Valves series from Bosch Rexroth and meters hydraulic flow for automated motion control. It is built to nominal size 10, and its W8 spool geometry works with a linear characteristic curve so commanded flow changes proportionally with the input signal. Under a 10 bar differential pressure the valve delivers a nominal flow of 100 L/min, yet it can pass up to 170 L/min where the circuit demands higher throughput. Ports A and B may be pressurized to 315 bar, supporting high-pressure drives in presses or injection machines. Electronic control is handled through a ±10 V command/actual interface, while the on-board amplifier runs on a 24 VDC supply that draws no more than 1.5 A, letting designers size power feeds and protection devices accurately.
An external pilot oil supply keeps the control stage isolated from load pressure, and the internal pilot oil drain returns fluid without extra hoses. The mounting interface follows ISO 4401-05-05-0-94, allowing direct installation on standardized subplates. Electrical wiring connects through a DIN EN 175201-804 plug, and the assembled unit achieves an IP65 ingress rating to withstand dust and water jets in industrial environments. NBR seals contain mineral hydraulic oil and maintain service life across typical temperature ranges. A ZDR 6 DP0-4X/40YM-W80 pressure reducing valve is integrated to stabilize the pilot pressure, securing consistent spool positioning during rapid command changes. Together these features make the valve suitable for precise, repeatable flow direction tasks in automated hydraulic systems.
