The 4WRTE10Q2-100P-4X/6EG24ETK31/A1M is manufactured by Bosch Rexroth within the 4WRTE Directional Control Valves series and meters hydraulic oil for automated motion control. Size 10 establishes the port spacing for standard subplates, while the ISO 4401-05-05-0-05 mounting pattern lets the unit bolt directly to NG10 manifolds. A rated flow of 90 l/min at a 5 bar control edge supports medium-capacity actuators, and the recommended maximum of 170 l/min defines the safe limit for rapid traverses. Operating pressure reaches 350 bar at ports P, A, and B to accommodate high-force cylinders, and the pilot oil return line can withstand 315 bar without affecting spool stability. Internal pilot supply and return, identified by the ET code, remove the need for external pilot hoses, and a pilot oil flow of 7 l/min across the full command range ensures quick response under closed-loop control.
A nominal 24 V DC supply powers the integrated electronics, and peak current consumption is 1.6 A so power modules can be sized accurately. Wiring is completed through a DIN EN 175201-804 plug in the K31 configuration, and command inputs use the A1 interface that converts a ±10 V signal into proportional spool movement. The flow characteristic coded P gives a linear relationship with a fine control section for precise positioning near zero. An IP65 protection class shields the enclosure from dust and low-pressure jets, and NBR seals contain mineral oil at the sliding edges. System oil must reach cleanliness class 18/16/13 under ISO 4406 to prevent erosion and sticking.
