The 4WRPEH6C3B04L-2X/G24K0/A1M proportional solenoid valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. The NG6 valve size supports compact manifold blocks, and the ISO 4401-03-02-0-05 mounting interface allows direct installation on standard subplates. A linear flow characteristic ensures predictable metering as the spool shifts, while the C3 spool symbol defines its porting pattern for directional control tasks. The unit delivers a rated flow of 4 l/min and sustains system pressures up to 315 bar on ports p, a, and b, making it suitable for medium-pressure actuators. Control electronics receive a differential command signal of ±10 V across an input resistance of 100 kΩ, so standard motion controllers can drive the valve without excessive load. A 24 V DC supply energizes the built-in solenoids, coordinating the hydraulic output with electrical commands during machine cycles.
Maximum tank port pressure is limited to 250 bar, protecting return lines and reservoir components under transient loads. The valve reaches its fail-safe position in 7 ms at zero pressure, enabling rapid shutdown sequences when power or command signals are lost. Electrical consumption does not exceed 40 W, which minimizes cabinet heat and power supply sizing. An IP65 protection class guards the enclosure against dust and low-pressure water jets, and the DIN 43563-AM6 connector with six signal pins plus protective earth provides a standardized wiring interface. NBR seals resist common mineral oils and maintain leakage control over the specified temperature range. Overall mass is 2.7 kg, permitting direct mounting without auxiliary support brackets. These characteristics combine to provide accurate, fast, and reliable proportional control of hydraulic cylinders and motors within automated production cells.
