The 4WRPEH10C5B100L-2X/G24K0/A1M proportional solenoid valve belongs to the 4WRP Solenoid Valves series and is produced by Bosch Rexroth. It meters hydraulic flow and pressure in automated machinery. The nominal size is 10, matching NG10 manifold cavities. The mounting pattern follows ISO 4401-05-04-0-94 so that it bolts to common subplates. A nominal flow of 100 l/min at a 70 bar differential supports mid-range actuator speeds. The p, a, and b ports withstand 315 bar to suit high-pressure circuits. The t port is restricted to 250 bar to protect tank lines. A response time of 25 ms or less enables accurate closed-loop motion. The ±10 V command signal lets a controller position the spool proportionally. Hysteresis not exceeding 0.2 % reduces steady-state error during fine positioning.
The valve electronics run from a 24 V DC supply. Maximum power consumption is 60 VA, minimizing thermal load in the cabinet. Supply ripple must stay below 2 V DC to avoid control drift. A 6P+PE plug to DIN 43563 provides the electrical interface with protective earth. The enclosure carries an IP65 rating, allowing installation in dusty or wet areas. A time-lag fuse rated at 2.5 A is required to shield the solenoid and amplifier from overcurrent. Hydraulic cleanliness must reach ISO 4406 class 18/16/13 to prevent spool wear. NBR seals are fitted to maintain compatibility with standard mineral oils.
