The 4WRAB6E06-1X/G24N9K4/MR belongs to the 4WRA Proportional Directional Valves series from Bosch Rexroth and meters hydraulic oil to control actuator speed and direction in automated machinery. By varying spool position proportional to an input current, it generates precise flow and pressure gradients for closed-loop motion control. It is built in size 6 (NG6) and attaches to a manifold by subplate mounting that follows the ISO 4401-03-02-0-05 pattern. Each P, A, B, and T port is drilled to 8 mm, which supports a maximum flow of 42 l/min. Lines a, b, and p withstand 350 bar, while the tank line t is limited to 210 bar, setting the working envelope for medium-pressure circuits.
The solenoid section operates on 24 V DC and is wired through a round six-pole plus protective earth connector designated K4. The enclosure reaches IP65, and the outer surface can rise to 150 °C during continuous duty. A concealed manual override identified by code N9 permits local spool shifting without exposing moving parts. The valve installs in any orientation, and NBR sealing material, marked M, resists common hydraulic oils. System filtration must keep fluid cleanliness at ISO 4406 class 20/18/15 to limit wear. The assembly weighs 2.0 kg, easing handling during installation or replacement.
