Product Overview
The Rexroth 4WRZ25W8-220-73/6EG24N9EK4/D3M (Material Number: R900968534) is a high-performance pilot-operated proportional directional valve from the renowned Rexroth WRZ series. Designed for precise control of flow direction and magnitude in industrial hydraulic systems, this valve features a 4-way, 3-position spool configuration with a W8 spool type, providing progressive flow characteristics for smooth acceleration and deceleration of actuators. The integrated proportional solenoid (EG24) enables stepless, infinitely variable control of spool position, making it ideal for applications requiring accurate velocity and position control of hydraulic cylinders and motors. With a nominal flow capacity of 220 L/min and a robust design, this valve is engineered for demanding continuous duty cycles in heavy industrial environments.
