Product Overview
The Rexroth 4WRZE 10 W6-85-73/6EG24N9ETK31/F1D3M (Material Number R900705138) is a high-response, pilot-operated proportional directional valve from the Rexroth WRZE series. It is designed to control the direction and magnitude of flow in hydraulic systems proportionally to an electrical input signal, enabling precise, infinitely variable control of actuator speed, position, and force. The valve features a size 10 (NG10) nominal bore, a spool with progressive flow characteristics, and an integrated on-board electronics module (OBE) with a central electrical connector. This valve is a critical control element in demanding industrial hydraulic circuits where accurate, repeatable, and dynamic motion control is required.
