The 4WRTE10V50L-4X/6EG24TK31/A1M valve is produced by Bosch Rexroth within the 4WRTE Directional Control Valves series and serves to regulate actuator speed and direction in hydraulic automation. Its nominal size NG10 defines port dimensions suitable for medium-flow manifolds, while a rated flow of 50 l/min supports continuous circuit demand without excessive pressure drop. A recommended maximum flow of 170 l/min covers short-term peak events, and a maximum operating pressure of 350 bar makes the unit compatible with high-pressure power packs. The T pilot oil version uses an external supply with an internal return, and a pilot oil flow of 7 l/min keeps the servo spool balanced during dynamic shifts. Response sensitivity not exceeding 0.05 % allows small signal changes to alter flow promptly, and hysteresis kept below 0.1 % minimizes deadband during repetitive positioning.
Electrical characteristics start with a 24 V DC supply that powers the integrated electronics, while a command input span of ±10 V lets motion controllers issue proportional flow commands. The valve draws up to 1.6 A and 72 VA, figures needed when sizing power supplies and monitoring heat load. Environmental protection is rated at IP65 so the housing resists dust ingress and water jets present in factory wash-downs. Wiring is handled through a plug conforming to DIN EN 175201-804, giving a standardized detachable electrical connection. NBR seals contain hydraulic fluid and tolerate common mineral oils used in industrial plants. A weight of 8.7 kg informs mounting hardware selection and assists with load calculations on subplates or manifolds, completing the specification set without adding extraneous data.
