The 4WRKE16E2-200L-3X/6EG24K31/A1D3M valve from Bosch Rexroth belongs to the 4WRKE Directional Valves series and directs hydraulic flow for proportional position control in automation systems. Its nominal size of 16 sets the spool and port dimensions used in NG16 manifolds. A mounting interface compliant with ISO 4401-07-06-0-94 allows block installation without additional adapters. The valve delivers a nominal flow of 200 L/min at a 10 bar differential, while a maximum permissible flow of 460 L/min supports short-duration peaks. Service ports P, A, and B withstand operating pressures up to 350 bar, and the T port tolerates return pressures up to 250 bar when connected externally. External pilot-oil supply ensures the pilot stage receives clean pressure, and external pilot-oil drain keeps pilot exhaust separate from the tank circuit.
Electronic actuation is supplied with 24 V DC, and a ±10 V command/actual value signal provides the proportional setpoint and feedback needed for closed-loop control. The DIN EN 175201-804 electrical connector presents a standardized interface for wiring power and signals. Peak electrical demand reaches 72 W, so cabinet power budgets must accommodate this load. An IP65 protection rating guards the enclosure against dust ingress and low-pressure water jets. Mechanical accuracy is supported by a maximum hysteresis of 1 %, limiting deviation between input voltage and spool position. Pilot pressure stability is maintained by the included ZDR 6 DP0-4X/40YM-W80 pressure-reducing valve. Overall unit mass is 11.2 kg, which affects mounting hardware selection and handling during service.
