The 4WRPH6C4B40P-2X/G24Z4/M valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series and is intended for hydraulic automation where electronic control of flow is required. Its nominal size 6 body fits compact power units, and the ISO 4401-03-02-0-94 mounting interface lets the unit bolt to standardized manifolds. A nominal flow of 40 L/min supports medium-capacity actuators, while the non-linear P flow characteristic provides sensitive regulation near the center position. The spool symbol C4 defines the land geometry that directs fluid between ports, and the valve withstands 315 bar at ports p, a, and b for high-pressure circuits. NBR sealing keeps hydraulic oil contained, and an IP65 enclosure rating blocks dust and water sprayed during normal machine operation.
The electrical section operates from a 24 V DC supply; a coil resistance of 2.5 Ω at 20 °C and a maximum solenoid current of 2.7 A set the magnetic force that shifts the spool. Power is routed through a DIN 43650 / ISO 4400 connector that includes two contacts plus protective earth. A 4-pin Pg7 connector handles position feedback, sending a 0 to 10 V transducer signal powered by an external ±15 V source limited to 35 mA. The tank port tolerates 250 bar, allowing elevated return pressure without damage. Together these hydraulic ratings and electrical limits define safe boundaries for proportional control of cylinder speed and force in automated systems.
