The 4WRPNH6C3B25P-2X/M/24PA6B valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series and is applied to modulate flow and pressure in hydraulic automation loops. It comes in a nominal size of 6, allowing integration into compact manifolds. A C3 spool shape defines the internal metering edges for precise bidirectional control, while the inflected P flow characteristic supports stable regulation across the stroke. With a rated flow of 25 l/min at a 70 bar differential, the unit suits medium-capacity actuators. Subplate mounting that follows ISO 4401 speeds installation onto standardized base plates. The hydraulic stage withstands operating pressures up to 315 bar so it can reside in high-pressure supply lines. Electronics draw 40 W from a 24 V DC source, balancing response speed with modest energy use. The assembly weighs 2.7 kg, which permits manual handling during maintenance.
A ±10 V command interface (A6) enables direct connection to common analog controllers, and a combined ±10 V and SSI sensor interface (B) returns spool position for closed-loop feedback. Continuous service is supported by a 100 % duty cycle, preventing thermal limitations during long operating sequences. Power and signal wiring terminate on an 11-pin plus protective earth connector conforming to EN 175201-804, simplifying harness assembly. The T port safely handles back-pressure up to 250 bar, protecting tank lines in counterbalance circuits. An IP65 protection class seals the enclosure against dust and water jets in industrial environments, while NBR sealing elements resist standard hydraulic oils without swelling.
