The 4WRPH6C4B12L-1X/G24Z4/M valve is part of the 4WRP Solenoid Valves series from Bosch Rexroth and is applied in hydraulic automation to modulate directional flow. It is built in size 6 (NG6) so it fits compact sub-plates, and it follows the ISO 4401-03-02-0-94 mounting pattern for standardized interface alignment. A linear flow characteristic enables proportional adjustment across its stroke, while a nominal flow of 12 l/min at a differential pressure of 70 bar supports moderate actuator speeds. The spool identified by symbol C4 sets the internal porting arrangement for circuit design. Operating pressure can reach 250 bar, making the unit suitable for medium-pressure systems. The solenoid is rated for a 24 V DC supply, and a coil resistance of 2.5 Ω at 20 °C establishes the base current draw needed for full actuation.
Maximum power consumption is limited to 35 VA, and the solenoid current must not exceed 2.7 A to avoid thermal overload. An IP65 degree of protection shields the enclosure from dust ingress and low-pressure water jets. The hydraulic medium must be maintained at ISO 4406 cleanliness class 18/16/13 or better to prevent wear of the metering edges. Internal position feedback relies on a transducer that requires 10 Veff at 7 kHz as its excitation signal. Electrical hookup uses a DIN 43650 connector with an M16×1.5 thread and a 2 + PE contact layout. The assembly withstands continuous vibration of 25 g along three axes for 24 hours, ensuring stability on mobile platforms or presses, and it has a mass of 2.2 kg, which allows single-person installation.
