The 4WRTE10V50L-4X/6EG24ETK31/A1M directional control valve belongs to Bosch Rexroth’s 4WRTE Directional Control Valves series and is used to regulate actuator movement in hydraulic automation systems. The NG10 valve size provides a passage area appropriate for medium-power circuits, while the ISO 4401-05-05-0-05 interface lets it bolt directly to a standard manifold. A 24 V DC electrical supply energizes the proportional coil, which draws up to 1.6 A so power supplies can be matched without oversizing. Overall electrical demand is limited to 72 VA, helping to manage panel heat. Wiring is completed through a DIN EN 175201-804 K31 connector that maintains pin consistency across machines. The housing meets IP65, allowing reliable service in wash-down or dusty locations. Internal pilot supply and return paths remove the need for external pilot lines and simplify plumbing.
The valve delivers a rated flow of 50 l/min with a 5 bar pressure drop per metering edge, giving predictable velocity control, yet it can handle up to 170 l/min when higher throughput is required. Ports P, A, and B tolerate 350 bar, so the component fits high-pressure presses and molding equipment. A 2.7 A impulse current is accepted during actuation to move the spool quickly, and the 100 kΩ input resistance minimizes load on the electronic controller. Continuous duty is supported up to a coil temperature of 150 °C, guarding against thermal damage. Circuit protection is provided by a 4 A time-lag fuse that opens on sustained overcurrent. The assembly weighs 8.7 kg, which should be considered when designing manifold supports and mounting brackets.
