Product Overview
The Rexroth 4WRLE16 E1Z-180SJ-3X /G24 K0/A1M (Material No. 0811404306) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth 4WRLE series. Engineered for precise control of flow direction and magnitude in demanding hydraulic systems, this valve features a size 16 (NG16) main stage with integrated position feedback and a nominal flow capacity of 180 L/min at a 10 bar pressure drop per land. The “E1Z” designation indicates an external pilot oil supply and external pilot oil return configuration, while the “SJ” spool type provides a specific progressive flow characteristic optimized for smooth acceleration and deceleration of actuators. The “3X” series denotes the current generation of this valve family, incorporating advanced manufacturing tolerances and enhanced spool-to-sleeve matching for superior metering accuracy. With a /G24 K0/A1M solenoid configuration, this valve operates on 24 V DC and includes an integrated amplifier module (A1M) with position control loop, enabling closed-loop operation when paired with an external position transducer. This valve serves as a critical interface between electronic control systems and hydraulic actuators, delivering exceptional dynamic response, minimal hysteresis, and repeatable performance in the most demanding industrial applications.
