The Bosch Rexroth 4WEH10JB4X/6EG24N9TK4/B10 (R900249159) is a sophisticated directional spool valve designed for electrohydraulic actuation, providing precise control over the start, stop, and direction of fluid flow. This model is built for subplate mounting and conforms to ISO porting patterns. It features a main valve with housing, control spool, return springs, and a pilot control valve equipped with one or two solenoids for efficient operation. The valve's main control spool can be held in its central position by either the return springs or through pressurization. The pilot oil can be supplied internally or externally and upon actuation of the pilot control valve, the spool shifts to connect or disconnect various ports within the main valve. An optional manual override is available for manual operation without solenoid power. This model offers various types of actuation including spring or pressure centering and spring end position or hydraulic end position. It accommodates wet-pin DC or AC solenoids and provides options for electrical connections either individually or centrally. Additional optional features include switching time adjustment, a preload valve in channel P of the main valve, stroke setting, and spool position monitoring. Notably, this directional valve comes with inherent internal leakage due to its design principle which may increase over its lifecycle. For applications requiring precise adjustments of pilot oil supply, an authorized specialist must implement modifications using components like throttle inserts to ensure optimal performance while adhering to maximum operating parameters specified in technical data sheets.
