The 4WRKE16E200L-3X/6EG24K31/A5D3M-280 is produced by Bosch Rexroth within the 4WRKE Directional Valves series and is used to meter flow and control actuator motion in hydraulic automation. A nominal size of 16 establishes the port geometry required for medium-capacity manifolds, while the ISO 4401-07-06-0-94 mounting interface lets technicians bolt the valve directly onto standardized subplates. Its electronics run on a 24 V DC supply voltage, and the ±10 V command signal allows proportional spool positioning from common analog controllers. The assembly tolerates 350 bar on ports p, a, and b, enabling operation in high-pressure circuits, and it withstands 250 bar on the return line to protect the tank port. A nominal flow of 200 L/min at a 10 bar differential defines base throughput, and hysteresis of no more than 1 % keeps position repeatability tight during directional changes.
The valve passes up to 460 L/min during transient flow peaks, so system designers can accommodate momentary demand surges without cavitation. Its internal driver dissipates no more than 72 W, and a maximum supply current of 1.5 A matches readily available power supplies. A plug conforming to DIN EN 175201-804 forms the electrical connection, and an IP65 protection class guards the housing against dust ingress and low-pressure water jets. NBR seal material maintains compatibility with standard hydraulic oils, and the integrated ZDR 6 DP0-4X/40YM-W80 pressure-reducing valve stabilizes the pilot stage. The complete unit weighs 11.2 kg, so mounting points must support that mass without deformation.
