The 4WRPNH6C4B40L-2X/M/24PF6G valve is manufactured by Bosch Rexroth within the 4WRP Solenoid Valves series and regulates flow in hydraulic automation systems. Its nominal size 6 layout fits compact manifolds, and the ISO 4401-03-02-0-05 mounting pattern aligns the ports for quick block installation. A linear flow characteristic simplifies proportional control because the output volume changes directly with command current. The rated flow reaches 40 l/min at a 35 bar differential per edge, providing medium-duty actuator supply. Electrical control is accepted through a 4–20 mA F6 interface, and the valve draws up to 40 W from a 24 VDC supply that may vary between 21 and 36 VDC. A mated connector seals the housing to IP65, preventing dust and low-pressure water from affecting the coil.
Hydraulic limits are defined by a 315 bar maximum on ports p, a, and b, while the tank port tolerates up to 250 bar to maintain safe return flow. The unit operates with mineral oils held between –20 °C and +60 °C, and it performs best when viscosity remains from 20 to 100 mm²/s to preserve film strength and response time. System filtration must achieve ISO 4406 18/16/13 cleanliness so that spool motion remains unobstructed by particles. The valve weighs 2.7 kg, allowing direct manifold mounting without reinforcement. Together, these limits define reliable duty in proportional pressure and flow circuits where continuous modulation is required.
