The 4WRTE10V50L-4X/6EG24ETK31/F1M is a directional control valve produced by Bosch Rexroth in the 4WRTE Directional Control Valves series for precise hydraulic automation. Its NG10 size defines the mounting envelope and supports circuit designs that require medium flow capacity. A rated flow of 50 l/min establishes the controllable volume passing through the metering slots during normal operation, while a maximum operating pressure of 350 bar allows the valve to handle high-pressure supply, actuator, and return lines. The spool provides a linear flow characteristic so flow changes proportionally with command signal, which simplifies closed-loop control. The ISO 4401-05-05-0-05 porting pattern matches standard subplates, reducing installation work. Both pilot oil supply and pilot oil return are internal, so no external pilot lines are needed and overall plumbing is minimized.
The electrical interface follows DIN EN 175201-804, enabling quick connection with a common industrial plug and cable. A nominal supply of 24 V DC energizes the solenoid; the valve remains functional between the lower limit of 18 V DC and the upper limit of 35 V DC to tolerate voltage variation in mobile or plant power buses. Maximum current consumption is 1.6 A, and total power draw is limited to 72 VA, parameters that help size power supplies and protect control electronics. An IP65 protection class seals the housing against dust ingress and low-pressure water jets, supporting use in harsh production areas. The recommended maximum flow of 170 l/min marks the upper boundary before dynamic behavior or pressure drop become unfavorable. The unit weighs 8.7 kg, a consideration for mounting brackets and service handling.
