The 4WRPEH6C3B40L-3X/M/24A1 valve is part of the 4WRP Solenoid Valves series from Bosch Rexroth and is designed to meter hydraulic oil in automation systems. It is built in nominal size 6 to fit compact manifolds and mounts on a subplate that follows the ISO 4401-03-02-0-05 porting pattern. A spool defined by symbol C3 provides the required flow paths, while four switching positions supply discrete control stages for machinery cycles. The metering edge delivers a linear flow characteristic so spool travel remains proportional to flow. A rated flow of 40 l/min supports medium-power circuits, and proportional solenoid actuation with position control holds the spool at the commanded position under varying load. Fluid cleanliness must meet ISO 4406 class 18/16/13 to avoid premature wear of precision parts.
Continuous service pressures reach 350 bar on ports a, b, and p, and the tank port withstands 250 bar. The solenoid operates from a 24 V DC supply, and the electronics accept a ±10 V command input for position reference. Electrical connection is through a 7-pole (6+PE) plug that complies with EN 175201-804, providing power, signal, and protective earth in one interface. NBR seals contain the hydraulic medium and tolerate common mineral oils, while the assembled unit weighs 2.9 kg, allowing manual installation and removal.
