The 4WRPNH6C4B15P-2X/M/24FA6C valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It regulates direction and flow of pressure media by moving a spool under proportional control. The unit follows Nominal Size 6 so it fits NG6 subplates in compact manifolds. A porting pattern of ISO 4401-03-02-0-05 aligns the body with common interface plates and simplifies service exchange. Its electronics accept a supply voltage of 24 VDC that powers the integrated amplifier. A PROFIBUS DP/V2 bus interface links the valve to central controllers for parameter setting and diagnostics, while a ±10 V command interface allows conventional analog control. Position feedback is available through the X4 ±10 V and X7 1 Vss sensor interface to close the servo loop. Dynamic behavior is supported by a step response of no more than 10 ms, and hysteresis stays within 0.2 percent for repeatable positioning.
The valve delivers a rated flow of 15 l/min across a 70 bar differential, matching medium-size actuator demands in presses and test rigs. An inflected P flow characteristic moderates spool gain around null to enhance fine motion control, and the C4 spool symbol specifies the port interconnections achieved at each command value. Service ports p, a, and b withstand pressures up to 315 bar, whereas the tank port t is limited to 250 bar to protect return lines. Internal leakage remains below 180 cm³ per minute at 100 bar, decreasing heat generation and fluid loss. Electrical power consumption does not exceed 40 W, reducing enclosure cooling requirements. An IP65 protection class shields the housing against dust and water jets for operation on exposed machinery.
