Product Overview
The Rexroth 4WRTE16E1-125L-46/6EG24K31/A1M is a high-response, pilot-operated proportional directional valve from the renowned 4WRTE series, engineered for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 16 (NG16) nominal bore, this valve utilizes a two-stage design where a proportional pilot valve actuates the main spool via hydraulic pilot pressure, enabling smooth, infinitely variable directional control with exceptional dynamic response. The integrated position feedback and electrical position transducer ensure high repeatability and minimal hysteresis, making it ideal for closed-loop applications requiring accurate velocity and position control. With a rated flow capacity of 125 L/min at a 10 bar pressure drop per land, this valve is a direct-fit replacement for OEM Rexroth installations and is widely deployed in high-performance hydraulic circuits across heavy industry.
