The 4WRPH6C3B40L-2X/G24Z4/M-561 proportional solenoid valve belongs to the 4WRP Solenoid Valves series and is manufactured by Bosch Rexroth. It modulates hydraulic flow and direction in automated machinery. The nominal size of 6 defines the interface envelope so it fits compact manifolds without additional adapters. Subplate mounting lets technicians remove the valve from a manifold block without disturbing pipework. The ISO 4401-03-02-0-94 porting pattern keeps the passage layout consistent with other size-6 modular valves. A rated flow of 40 l/min allows moderate actuator velocities in mid-capacity systems. The linear flow characteristic yields a proportional relation between spool position and flow rate, which facilitates precise command scaling. An LVDT (DC/DC ±10 V) position transducer feeds actual spool position to the controller for closed-loop operation. The 24 VDC supply voltage aligns with common industrial power rails, and a maximum power draw of 40 VA limits heat dissipation in electrical cabinets.
The valve withstands a maximum operating pressure of 315 bar on ports P, A, and B, enabling use in high-pressure circuits, while the tank port is limited to 250 bar to safeguard return-line components. Spool symbol C3 defines the internal metering edges so circuit designers can predict flow paths under each command. A peak solenoid current of 2.7 A sets the rating for the drive amplifier, and a coil resistance of 2.5 Ω at 20 °C determines steady-state current when the coil is energized. The electrical interface is an EN 175301-803 connector with two power pins and a protective earth, providing quick disconnection during service. Oil cleanliness must meet ISO 4406 (18/16/13) to prevent wear on the precision spool assembly. The valve body weighs 2.3 kg, allowing installation without lifting equipment.
