The 4WRLE16Q5-200M-3X/G24K0/A1M proportional valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and is used to regulate flow and pressure in closed-loop hydraulic automation. It accepts a ±10 V command signal that shifts the spool with proportional accuracy, while the internal electronics draw 40 VA from a 24 V DC supply to energize the solenoid. A nominal flow capacity of 200 l/min supports steady circuit demand, and a peak flow capability of 800 l/min permits short-term acceleration of actuators. The manifold interface follows the ISO 4401-07-07-0-05 pattern so the unit can mount directly on standardized subplates. Reliable actuation is maintained once pilot pressure reaches 10 bar, and the design is rated for a 100 percent duty cycle so it may remain energized without thermal delays.
For system safety, the valve body withstands 270 bar at ports P, A, and B, and holds the same 270 bar at pilot port X, while the tank return ports T and Y are limited to 210 bar. Fluid cleanness must not exceed ISO 4406 code 18/16/13 to prevent spool sticking and wear. An IP65 enclosure protects the coil and connector against dust ingress and low-pressure water jets, so cabinet mounting is not mandatory. The assembly may be installed in any orientation, giving designers freedom in crowded manifolds. NBR sealing elements contain standard mineral-oil media and resist common hydraulic additives. Total mass is 12 kg, a consideration for support brackets when the valve is suspended on pipework.
