The 4WRPEH6C3B12L-2X/G24K0/A1M-817 proportional solenoid valve is manufactured by Bosch Rexroth as part of the 4WRP Solenoid Valves series and regulates flow and pressure in hydraulic automation circuits. Its spool symbol is C3, the nominal size is 6 (NG6), and the mounting pattern follows ISO 4401-03-02-0-05 for direct manifold assembly. A nominal flow of 12 l/min is achieved at a 70-bar pressure drop, while ports P, A, and B withstand up to 315 bar and the tank port endures 250 bar. Control electronics accept a ±10 V command and draw a maximum of 40 VA from a 24 V DC supply to position the spool accurately.
A 6 + PE connector compliant with DIN 43563 provides the electrical interface, and a 2.5-amp slow-acting fuse protects the incoming line. Supply ripple must remain below 2 V DC, and valve hysteresis is limited to 0.2 percent to maintain precise actuator response. Internal leakage from port P to A is restricted to 50 cm³ per minute at 100 bar, reducing energy loss during standby. The enclosure carries an IP65 rating for dust-tightness and protection against water jets, yet the complete assembly weighs only 2.7 kg, allowing easy handling during installation.
