The 4WRVE25V300P-2X/G24KO/B5M directional control valve belongs to the 4WRVE Solenoid Directional Control Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks such as closed-loop position or velocity control. With a nominal size of NG25, the unit fits mounting patterns common to medium-flow manifolds. A nominal flow of 300 l/min at a 10 bar differential pressure provides predictable actuator speed, while an upper flow capability of 900 l/min accommodates transient peaks or low-restriction circuits. Flow characteristic code P defines the spool geometry used to generate a linear relationship between command voltage and flow. The valve accepts a ±10 V setpoint so it can interface directly with proportional amplifiers, and its 100 kΩ input impedance prevents excessive loading of the signal source. Solenoids are powered from a 24 V DC supply, and overall power consumption is 30 VA when fully energized.
Maximum working pressure at ports p, a, and b reaches 350 bar, enabling the valve to operate in high-pressure servo systems, whereas ports t, x, and y are limited to 250 bar to protect return and pilot lines. The pilot stage remains stable once 10 bar is available, ensuring reliable spool positioning during low-flow conditions. Control oil enters through external port X and leaves through external port Y so that pilot flow can be filtered or cooled separately from the main circuit. An 11P+PE connector according to DIN 43563-AM6 provides the electrical interface, and the housing is sealed to an IP65 degree of protection to resist dust and water spray. Total mass is 18.2 kg, making rigid manifold support important during installation.
