The 4WRPEH6C3B40L-2X/G24K0/A1M proportional solenoid valve is produced by Bosch Rexroth in the 4WRP Solenoid Valves series and is intended to regulate hydraulic flow and pressure in automated machines. Its nominal size of NG6 allows installation in compact manifolds, and the ISO 4401-03-02-0-05 mounting pattern aligns with standard subplates for straightforward setup. A nominal flow rate of 40 l/min at a 70 bar differential supports medium-capacity cylinders, while a maximum pressure of 315 bar on the P, A, and B ports enables operation in high-pressure circuits. The valve uses a linear flow characteristic to give proportional response as the spool shifts, and the C3 spool symbol defines internal port connections for bidirectional actuation. A ±10 V command input interfaces directly with common motion controllers, the solenoid coil is powered by 24 V DC, and power consumption remains below 40 VA to minimize electrical load.
A response time of 10 ms for a full-scale signal change allows the valve to follow rapid setpoint commands, and hysteresis limited to 0.2 % keeps position error low during direction changes. The IP65 protection class, achievable when the correct connector is fitted, guards the electrical section against dust and water jets in typical factory settings. An ambient temperature limit of 50 °C supports use near warm hydraulic reservoirs, while NBR seals tolerate common mineral oils and maintain elasticity under continuous duty. The T port withstands back-pressures up to 250 bar so return lines can carry elevated pressure without damaging the housing. A weight of 2.7 kg permits single-person handling during assembly, completing a specification set that enables precise and stable flow modulation in hydraulic automation.
