The 4WRPH6C3B24L-2X/G24K0/M-784 proportional valve belongs to the 4WRP Solenoid Valves series from Bosch Rexroth and is used to regulate pressure and flow in hydraulic automation loops. A nominal size of 6 (NG6) defines the port geometry, while the ISO 4401-03-02-0-94 mounting pattern lets the unit bolt directly to a standard subplate. Its C3 spool symbol sets the internal flow paths for bidirectional actuation, and a linear flow characteristic permits proportional control across the stroke range. The valve passes up to 24 l/min at a 70 bar differential, supporting medium-capacity circuits. Continuous service is allowed at 315 bar on ports P, A, and B, with port T limited to 250 bar for safe tank return. NBR seals provide compatibility with common mineral hydraulic oils.
The trigger electronics operate from a 24 V DC supply, and a coil resistance of 2.5 Ω at 20 °C determines the baseline current draw. Control authority reaches a maximum solenoid current of 2.7 A, giving a wide modulation range. A 10 ms 0–100 % response time allows fast pressure or flow changes, and hysteresis remains below 0.2 % to keep commanded positions repeatable. Spool position feedback is supplied by an LVDT DC/DC transducer, enabling closed-loop operation without external sensors. An IP65 degree of protection shields the assembly from dust and water jets during in-plant service, and the complete housing weighs 2.3 kg, easing manifold mounting and maintenance.
