The 4WRPEH6C3B24L-3X/M/24A1 valve is part of the 4WRP Solenoid Valves series from Bosch Rexroth and serves to modulate flow and pressure in hydraulic automation circuits. Nominal size 6 defines its compact mounting envelope for manifolds and subplates, while the ISO 4401-03-02-0-05 porting pattern aligns with standard surfaces for quick installation. A rated flow of 24 l/min at a 35 bar pressure drop per edge allows the valve to supply medium-capacity actuators without excess restriction. The linear flow characteristic provides proportional response to spool travel, and the C3 spool symbol specifies metering geometry that balances both service ports. Maximum pressure capability reaches 350 bar on ports p, a, and b, whereas the return port t is limited to 250 bar to protect tank lines. NBR seals are fitted to maintain leak tightness when exposed to common mineral hydraulic oils.
The integrated electronics operate from a 24 V DC supply, and a tolerance band of 19 to 36 V DC permits continued function during supply fluctuations. A ±10 V command signal input allows proportional control by standard analog controllers, and all wiring is handled through a 7-pin (6+PE) EN 175201-804 connector. When this connector is mated, the assembly achieves IP65 protection so it withstands dust and fluid splash in typical machine rooms. Approved hydraulic fluid temperatures from −20 to +70 °C enable use in both cold starts and elevated ambient conditions, while a recommended viscosity range of 20 to 100 mm²/s keeps flow characteristics predictable throughout service life.
