Product Description
Rexroth R900974817 4WRAE6W1-30-23/G24K31/F1V
The Rexroth R900974817, model 4WRAE6W1-30-23/G24K31/F1V, is a direct operated proportional directional valve designed for precise hydraulic control in various industrial applications. It features integrated electronics (OBE) and electrical position feedback, ensuring accurate spool positioning and responsive flow regulation. This size 6 (NG6) valve is built for subplate mounting according to ISO 4401 standards and offers a nominal flow rate of 30 liters per minute. The ‘W1’ spool configuration provides specific flow paths (P→T with A & B blocked in the neutral position; P→A/B→T and P→B/A→T when actuated). It operates on a 24V DC power supply and is equipped with FKM (Viton) seals, making it compatible with a wide range of hydraulic fluids and suitable for demanding operational conditions.
