4WRVE16V200L-2X/G24K0/B5M

The 4WRVE16V200L-2X/G24K0/B5M valve belongs to the 4WRVE Solenoid Directional Control Valves series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It regulates flow direction and magnitude through an electro-proportional spool driven by solenoids and internal position feedback. The valve weighs 10.4 kg, a value that affects manifold support requirements during installation. An IP65 degree of protection keeps internal electronics sealed against dust and low-pressure water jets, enabling operation in typical industrial environments. The solenoids are energized with a 24 V DC supply voltage, so standard machine power rails can be used. Control electronics plug into an 11P+PE connector, which groups command, feedback, and ground conductors in a single interface to simplify wiring. The control card expects a ±10 V input signal, allowing direct connection to common motion controllers; a 100 kΩ input impedance minimizes the load on those outputs. A matching ±10 V feedback signal is generated by the integrated position transducer, allowing the host controller to verify spool position. The spool’s L linear flow characteristic ensures proportional flow changes in response to command voltage, which helps tune stable position or speed loops in hydraulic cylinders.

Internally the valve uses a V 4/3-way spool, so ports P, A, B, and T are connected in three centered positions to control bidirectional actuator flow or to block lines when centered. With a nominal flow capacity of 200 l/min at a 10 bar differential, the unit handles medium to high flow demands without excessive pressure drop. Working ports P, A, and B tolerate continuous pressures up to 350 bar, permitting use in high-pressure systems, while pilot and drain ports t, X, and Y are limited to 250 bar for safe return or external pilot routing. Reliable spool movement requires at least 10 bar of control oil pressure, assuring stable piloting even under low system load. The ISO 4401-07-07-0-05 mounting pattern lets the valve drop onto standardized subplates, reducing custom manifold work. Acceptable oil viscosity extends to 800 mm²/s, which allows cold-start operation with thicker fluids. Cleanliness must reach ISO 4406 18/16/13, so filtration must be sized to keep particulate contamination below that coding to maintain valve accuracy and service life.
