The 4WRPNH6C3B40L-2X/M/24FA6T proportional solenoid valve is manufactured by Bosch Rexroth in the 4WRP Solenoid Valves series. It meters hydraulic oil to actuators for automated motion control. The valve is built to nominal size 6, so it mounts on compact manifolds and handles moderate flow demands. Its C3 spool provides a linear flow characteristic, giving predictable change in flow when the command signal varies. A rated flow of 40 l/min at a 70 bar differential supports cylinders that require steady medium volume. The unit withstands operating pressures up to 315 bar, while port T tolerates return pressures up to 250 bar, so back-pressure does not disturb regulation. An IP65 protection class seals the housing against dust and low-pressure water jets. Overall weight is 2.7 kg, which simplifies manual installation on stack subplates.
Dynamic behavior is supported by an actuating time of no more than 10 ms, enabling fast closed-loop corrections in servo hydraulic loops. Hysteresis remains within 0.2 percent, minimizing deadband and improving repeatability of flow control. The valve accepts a ±10 V command interface labeled A6, so standard analog motion controllers can drive it without extra scaling hardware. Internal electronics draw up to 40 W from a 24 V DC supply, balancing response speed with power consumption. A port pattern conforming to ISO 4401-03-02-0-05 ensures interchangeability with common subplate layouts. Fieldbus monitoring is available through an M12 five-pin Profibus connector at X3, and position feedback can be taken from an EnDat 2.2 sensor connection at X7, simplifying integration into digital machine networks.
