The 4WRPH6C3B04L-1X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth to meter flow in hydraulic automation circuits. It follows nominal size 6 and uses the ISO 4401-03-02-0-94 mounting pattern to fit NG6 subplates. The spool is identified by symbol C3 and has a linear flow characteristic, so displacement of the spool produces proportional flow. Under a differential pressure of 70 bar the valve delivers a nominal flow of 4 l/min, while ports P, A, and B are permitted to see up to 315 bar and port T is limited to 250 bar. Electrical actuation is provided by a 24 V DC supply; the coil draws up to 2.7 A and has a resistance of 2.5 Ω at 20 °C, allowing predictable current control from standard drivers.
Continuous service is possible because the duty cycle is rated at 100 % ED, so the assembly can remain energized without timed cool-down periods. Spool position is monitored by an AC/AC LVDT transducer that feeds displacement data to external electronics through a Pg7 four-pin connector, enabling closed-loop control. Power is routed to the solenoid by a DIN 43650/ISO 4400 plug with two power pins and a protective earth, and the housing meets IP65 to resist dust and low-pressure water. The complete unit weighs 2.3 kg, which simplifies handling during manifold installation and keeps overall system mass low.
