The 4WRPEH6C4B02L-3X/M/24A1 valve is manufactured by Bosch Rexroth within the 4WRP Solenoid Valves series. It controls directional and proportional flow in hydraulic automation. The unit is built for subplate mounting and follows the ISO 4401-03-02-0-05 porting pattern with a nominal size 6 interface. Electronic control is achieved through a ±10 V command signal coded A1, while a 24 V DC supply energizes the solenoid. To protect the circuit an external 2.5 A fuse is specified. Spool type C4 influences metering characteristics, and the position transducer is located on side B for feedback. The valve endures system pressures up to 350 bar on ports P, A, and B, and 250 bar on the tank line. Maximum power draw is 40 VA, allowing compact cabinet design.
The 4WRPEH6C4B02L-3X/M/24A1 operates with HL, HLP, HLPD, HVLP, HVLPD, or HFC fluids, ensuring compatibility with mineral oils and water-glycol blends common in mobile and industrial machinery. An IP65 enclosure, provided the plug is secured, shields the electronics from dust and low-pressure jets, so the valve can be installed in exposed locations where relative humidity reaches up to 95 % without condensation. The solenoid winding may reach 150 °C at continuous duty, and this temperature limit defines cooling requirements in tight manifolds. The body weighs 2.9 kg, which supports manual handling during maintenance without lifting equipment. These characteristics complete the operating envelope and confirm suitability for precise pressure and flow regulation in closed-loop servo circuits.
