The 4WRPH10C1B100P-2X/G24K0/M-750 valve belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and provides proportional directional control for hydraulic automation. It is actuated by a proportional solenoid that works with an external amplifier, allowing stepless spool positioning for precise flow adjustment. A supply voltage of 24 V DC drives the coil, which presents a resistance of 2.4 Ω at 20 °C and accepts a peak current of 3.7 A. Maximum electrical demand is 40 VA, so power modules must accommodate this load. The unit is delivered with a K0 electrical interface that leaves the mating connector to be selected separately. Nominal size 10 matches standardized medium-flow cavities, and the ISO 4401-05-04-0-94 porting pattern simplifies manifold integration. The spool follows symbol C1 and returns to a 4/4 fail-safe position if power is lost.
At a 70 bar pressure drop the valve provides a nominal flow of 100 l/min, and it can pass the same 100 l/min as its maximum capacity to support mid-range cylinder and motor circuits. Working ports P, A, and B withstand pressures up to 315 bar, while the tank port is rated for 250 bar, defining safe system limits. The inflected flow characteristic P supplies finer metering around the neutral region, which is important for smooth motion control. Hysteresis is held below 0.2 %, so commanded positions are repeated accurately during cyclic operation. These hydraulic figures let designers combine the valve with closed-loop controllers for stable speed and force regulation in presses, plastics machinery, and other automated equipment.
