The 4WRAB6E12-1X/G12N9K4/MR proportional directional valve belongs to the 4WRA Proportional Directional Valves series manufactured by Bosch Rexroth for closed-loop hydraulic automation. It meters oil to actuators with a maximum flow of 42 l/min so cylinders or motors receive stable volume at varying commands. Ports A, B, and P tolerate operating pressures up to 350 bar, allowing the unit to control high-pressure work circuits without external pressure reducers. The valve fastens by subplate mounting on an ISO 4401-03-02-0-05 interface, and the mounting screws require 7 Nm of torque to secure the housing against leakage. Electrical power and spool position signals enter through a 2-pole + PE connector in Design A format, while a concealed N9 manual override lets technicians shift the spool during commissioning or power loss. Internal sealing uses NBR material, providing compatibility with standard mineral hydraulic oils and resisting swell during continuous duty.
An IP65 protection class keeps the solenoid enclosure dust-tight and guarded against low-pressure jets, so the valve can be installed on machinery exposed to washdown. Ambient temperatures may reach 80 °C, and hydraulic fluid can run as hot as 70 °C without causing drift, while the surface temperature is limited to 150 °C to avoid damage to adjacent components. The cleanliness level of the working fluid must remain at ISO 4406 20/18/15 to protect the precision spool lands from abrasion. Operation is permitted at relative humidity up to 95 percent, letting the electronics perform in damp plant environments. Return-line port t withstands 210 bar, enabling back-pressure-controlled circuits without risk of cavitation. The assembled valve weighs 2.0 kg, so it can be handled and replaced by a single maintenance worker without lifting equipment.
