The 4WRPH6C4B04L-2X/G24Z4/M valve is produced by Bosch Rexroth within the 4WRP Solenoid Valves series and functions as a proportional directional element in hydraulic automation. The size 6 designation defines the port pattern used on compact subplate circuits, while spool symbol C4 specifies the internal land arrangement that directs flow paths. A nominal flow of 4 l/min delivers stable volume for small actuators, and a linear flow characteristic keeps the output proportional to the control signal. A 24 V DC supply energizes the solenoid, with a coil resistance of 2.5 Ω at 20 °C determining baseline current. Electrical input is limited to a maximum solenoid current of 2.7 A, and a 100 % ED duty cycle permits continuous energization without thermal rest periods.
The valve draws no more than 40 VA, keeping power supply requirements moderate. It installs on an ISO 4401-03-02-0-94 interface, so replacement and interchangeability with other size 6 components are straightforward. Ports P, A, and B tolerate pressures up to 315 bar, while the tank port T is rated for 250 bar, covering most industrial circuit demands. An IP65 protection class shields the coil assembly from dust and water jets when the DIN 43650 (ISO 4400) 2 + PE connector is fitted. NBR seal material provides compatibility with standard mineral oils, and the mass of 2.3 kg allows easy handling yet adds inertia against vibration. These combined parameters position the valve for precise, durable flow control in automated machinery.
