The 4WRPH6KB50P-2X/G24Z4/M valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth. It regulates hydraulic flow in automated machinery by shifting a size 6 spool, a dimension that matches compact manifold layouts. The ISO 4401-03-02-0-94 mounting pattern aligns the ports with standard subplates for quick replacement. A maximum flow rate of 40 l/min defines the volume it can meter without excess pressure loss. Its electromagnetic stage operates from a 24 VDC supply; the 2.5 Ω coil resistance limits steady-state power dissipation, while a peak solenoid current of 2.7 A sets the drive requirement for full stroke. Continuous energization is possible because the coil is rated for 100 % duty. A response time of 10 ms from 0 to 100 % command supports fast closed-loop pressure or position cycles.
The hydraulic body tolerates operating pressures up to 315 bar on the pressure and work ports, and the T port can withstand back pressure to 250 bar, enabling use in high-duty servo loops. An IP65 enclosure rating seals the assembly against dust and water jets for reliable service on mobile or industrial equipment. Electrical connection to the coil is made through a DIN 43650/ISO 4400 plug, while a separate Pg7 four-pin connector links the integrated position transducer. That sensor receives a ±15 V supply at 35 mA and returns a ±10 V feedback signal so external electronics can monitor spool displacement. At 2.3 kg the unit adds minimal mass to compact manifolds, easing installation by a single technician.
