The 4WRA6WA30-2X/G24N9K4/V-589 proportional directional valve belongs to the 4WRA Proportional Directional Valves series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. The valve size is 6, giving port centers that fit compact manifolds. It mounts on a subplate so line connections remain undisturbed during service. The porting pattern follows ISO 4401-03-02-0-05, enabling interchange with other standard valves. A port diameter of 8 mm on the pressure, work, and tank ports governs flow velocity and pressure drop. A nominal flow of 26 l/min covers typical cylinder or motor duties under rated conditions. The design can pass up to 42 l/min when higher transient speeds are required. Maximum permitted pressure is 350 bar on the pressure and work ports, while the tank line is limited to 210 bar to protect return components.
The solenoid operates from a 24 V DC supply, ensuring consistent spool positioning from common machine power rails. An IP65 protection class seals the coil housing against dust and low-pressure water jets encountered in factory environments. A concealed manual override lets technicians shift the spool mechanically without compromising enclosure integrity. Electrical connection is made through a 2-pole plus PE Design A connector, supporting quick replacement. FKM seals provide chemical resistance to conventional hydraulic oils and allow operation with elevated fluid temperatures. The external surface may reach 150 °C, so adjacent wiring and hoses must be heat-rated accordingly. Fluid cleanliness must meet ISO 4406 20/18/15 to limit abrasion and maintain proportional accuracy. With a mass of 2.0 kg, the valve can be installed by one person without lifting aids.
