4WRPH6C3B15P-2X/G24Z4/M

The 4WRPH6C3B15P-2X/G24Z4/M proportional directional valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth for hydraulic automation tasks that require precise flow and pressure modulation. It operates from a 24 V DC supply, allowing direct connection to common machine controllers, while a coil resistance of 2.5 Ω establishes the electrical load presented to the drive card. A rated solenoid current of 2.7 A defines the maximum command signal that can be applied without overheating, and a 100 % ED duty cycle permits the coil to remain energized indefinitely during closed-loop positioning sequences. The built-in LVDT DC/DC position transducer returns continuous spool feedback to the amplifier to maintain accurate flow regulation, and the P-shaped inflected flow characteristic provides a predictable relationship between command signal and flow rate. With a nominal flow of 15 l/min, the valve is sized for small actuators or pilot stages, while the size 6 form factor keeps envelope dimensions compact in manifold assemblies.

The ISO 4401-03-02-0-94 mounting pattern lets the valve bolt to standard subplates, streamlining replacement and circuit layout. An IP65 degree of protection seals the housing against dust and low-pressure water jets, supporting reliable operation in industrial wash-down zones. NBR seals are fitted to ensure compatibility with common mineral oil hydraulic fluids. The work ports tolerate pressures up to 315 bar, and the tank port rating of 250 bar prevents case drain over-pressure in high-back-pressure systems. Electrical hookup is via a DIN 43650/ISO 4400 (2+PE) connector, enabling quick coil changes or testing. The C3 spool symbol defines the neutral overlap and flow paths used in directional control logic. Finally, a weight of 2.3 kg allows single-person installation without special lifting equipment.
