The 4WRPH6C3B12L-2X/G24K0/M-784 valve belongs to the 4WRP Solenoid Valves series from Bosch Rexroth. It meters hydraulic flow in closed-loop automation tasks by using a proportional spool controlled by an integrated solenoid. The valve operates on a 24 V DC supply voltage so that it can be wired directly to common machine control power rails. During normal duty the solenoid draws 2.7 A and therefore the electrical power consumption is 40 VA, values that help designers size power supplies and drivers. The unit conforms to the ISO 4401-03-02-0-94 mounting pattern, allowing direct stacking on NG6 subplates without adapter blocks. A nominal size of 6 supports compact manifolds while still providing a nominal flow rate of 12 l/min for medium-capacity actuators. The spool is identified by symbol C3, delivering a linear flow characteristic that simplifies open-loop command scaling. Closed-loop positioning error is minimized because hysteresis is no more than 0.2 %, which stabilizes cylinder motion at small signal changes.
The valve withstands service conditions found on mobile and industrial equipment. A protection rating of IP65 shields internal parts from dust and low-pressure water jets so cabinet enclosure is optional. Ports p, a, and b may be pressurized up to 315 bar while the tank port t is limited to 250 bar, limits that define the maximum system pressure for safe operation. The sealing system is based on NBR material to resist common hydraulic oils. A transducer fitted on side B feeds back spool position to the control loop, enabling precise flow regulation. Tested vibration resistance of 25 g prevents false signals or mechanical wear in high-shock environments. The assembly weighs 2.3 kg, light enough for manifold mounting without extra support.
