Product Overview
The Rexroth 4WRTE35E1-1000L-46/6EG24K31/A1M (Material Number: R901077004) is a high-performance, pilot-operated proportional directional valve with electrical position feedback and integrated on-board electronics (OBE). Designed and manufactured by Bosch Rexroth, this valve is part of the renowned 4WRTE series, which is engineered to deliver precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. The valve operates on a two-stage principle: a pilot stage (controlled by a proportional solenoid) directs pilot pressure to actuate the main spool of the second stage, thereby regulating the flow of hydraulic fluid to the actuator. The integrated OBE simplifies system integration by eliminating the need for external amplifiers, while the electrical position feedback ensures high repeatability and precise spool positioning. With a nominal flow capacity of 1000 L/min and a size 35 (NG35) interface, this valve is ideally suited for high-flow, high-precision applications where accurate velocity and position control of hydraulic actuators is critical.
