The 4WRPEH6C3B12L-2X/G24K0/B5M valve belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and meters hydraulic flow in automated machinery. With a nominal size of 6, it suits compact manifolds, and its rated flow of 12 l/min at a 70-bar differential delivers predictable actuator speed. A linear flow characteristic links solenoid current directly to flow change, and a maximum operating pressure of 315 bar on ports P, A, and B allows use in high-pressure circuits. The ISO 4401-03-02-0-05 porting pattern fits standard subplates to simplify installation. Continuous duty is supported by a 24 V DC coil specified for a 100 % ED duty cycle, while a 6P+PE plug compliant with EN 175201-804 provides the electrical interface and grounding.
An IP65 protection class is achieved when a mating connector is installed, guarding the enclosure against dust and water. Spool position is monitored by an inductive transducer so the control system can maintain closed-loop accuracy. Hydraulic fluid must meet ISO 4406 (c) 18/16/13 cleanliness to prevent wear and feedback errors. The coil’s surface may reach 150 °C during continuous energization, defining thermal limits for adjacent components. Seal integrity at pressure and tank ports is maintained by 9.25 × 1.78 mm O-rings, and the assembly weighs 2.9 kg, making it easy to handle while providing sufficient mass to resist vibration.
