The Rexroth 4WRA6E15-23/G24N9K4/V (Bosch Rexroth R900920557) is a direct operated proportional directional control valve, size NG6, designed for subplate mounting according to the ISO 4401-03-02-0-05 standard. This valve precisely controls the direction and magnitude of hydraulic fluid flow through proportional solenoid actuation and operates without electrical position feedback. The ‘E’ spool configuration ensures that ports P, A, B, and T are blocked in the spring-centered neutral position, providing P-A/B-T and P-B/A-T flow paths when the respective solenoids are energized. Key features include a 24V DC solenoid, no manual override (N9 designation), a K4 type electrical connector compliant with DIN EN 175301-803, and FKM (Viton) seals for compatibility with a wide range of hydraulic fluids and operating temperatures. This valve is well-suited for various industrial hydraulic applications requiring accurate flow control.
