The 4WRKE16W6-200L-3X/6EG24TK31/A1D3M is a model produced by Bosch Rexroth within the 4WRKE Directional Valves series for controlling flow and direction in hydraulic automation circuits. It is built to the ISO 4401-07-06-0-94 porting pattern, and its nominal size is 16. A command signal of ±10 V positions the spool, while a 24 V DC supply drives the electronics with a maximum supply current of 1.5 A. The valve consumes up to 72 W during operation and carries an IP65 protection rating against dust and water. Its mass is 11.2 kg, which supports straightforward handling and installation.
The unit withstands operating pressures up to 350 bar at ports P, A, and B and allows a maximum flow of 460 L/min. Under a 10 bar differential, the nominal flow reaches 200 L/min. Pilot oil is supplied externally and drained internally, and the pilot valve return line must remain below 10 bar. A pressure reducing valve designated ZDR 6 DP0-4X/40YM-W80 regulates pilot pressure, and NBR seals provide fluid compatibility.
