The 4WRKE10W6-50L-3X/6EG24TK31/A5D3M directional valve belongs to the 4WRKE Directional Valves series from Bosch Rexroth and is used to regulate flow and direction in hydraulic automation loops. Its nominal size of 10 suits compact NG10 manifolds, while a nominal flow of 50 L/min at a 10 bar pressure drop supports consistent actuator motion in medium-capacity circuits. When higher demand occurs, the main stage can pass up to 170 L/min without exceeding design limits. The assembly tolerates 315 bar on both the main ports and the pilot supply, enabling use on high-pressure systems without separate pressure reduction devices. Electronics run from a 24 V DC supply, receive a ±10 V command signal for spool positioning, and return an actual value of ±10 V for feedback control. Internal power consumption peaks at 72 W, which must be considered when sizing the electrical cabinet.
The valve interfaces with subplates through the ISO 4401-05-05-0-94 porting pattern, allowing direct swap with other NG10 components. Electrical hookup is completed with a DIN EN 175201-804 connector, and the enclosure carries an IP65 rating that blocks dust and water spray during routine wash-down. Pilot oil is supplied externally to let the control stage operate at a stable pressure, while pilot oil drains internally so no additional return line is needed. Required fluid cleanliness is ISO 4406 (c) 20/18/15 to preserve spool accuracy and service life. The complete assembly weighs 8.7 kg, which affects mounting arrangements and handling equipment during installation.
