The 4WRPH10C1B100P-2X/G24Z4/M is a solenoid valve in the 4WRP Solenoid Valves series produced by Bosch Rexroth for precise flow control in hydraulic automation. It fits NG10 manifolds because its nominal size is 10, and at a differential pressure of 70 bar it provides a nominal flow of 100 l/min. Ports P, A, and B handle working pressures up to 315 bar, while the spool follows a P-shaped inflected flow characteristic for proportional response. A 24 V DC supply energizes the coil, drawing 60 VA during normal duty. Coil resistance at 20 °C measures 2.4 Ω, and the drive circuit limits current to 3.7 A to protect the winding.
The enclosure carries an IP65 rating for dust-tight sealing and water jets, and wiring is completed through a DIN 43650/ISO 4400 connector. Mounting uses the ISO 4401-05-04-0-94 porting pattern, enabling direct installation on standardized subplates. A DC/DC LVDT with a ±10 V signal supplies spool position feedback for closed-loop control, and static hysteresis is kept at or below 0.2 % to maintain repeatability. The tank port withstands 250 bar, matching auxiliary circuit demands. Reliable operation is supported across ambient temperatures from ‑20 °C to +50 °C.
