The Bosch Rexroth 4WEH 16 G7X/6EG24N9ETS2K4 (R900930093) is a sophisticated directional spool valve designed for electrohydraulic actuation, adept at managing the initiation, cessation, and direction of fluid flow. This high-performance valve is integral to systems requiring precise control over hydraulic functions and is characterized by its robust construction which includes a housing, a main control spool, return springs, and a pilot control valve equipped with solenoids. The main control spool's default position is centrally held by the return springs or through pressurization. The 4WEH series valves are highly versatile and can be tailored to specific applications through options such as spring or pressure centering, various types of solenoids (wet-pin DC or AC), and multiple electrical connection styles. Additional customization features include manual overrides, switching time adjustments, preload valves in channel P of the main valve, as well as stroke setting and spool position monitoring capabilities. The valve's pilot oil supply can be configured either internally from channel P or externally via port X depending on the model variant. Similarly, pilot oil return can be routed internally through channel T or externally through channel Y. These configurations ensure adaptability to different system requirements. It's important to note that any alterations to the pilot oil supply should only be undertaken by qualified personnel to maintain system integrity and performance. This model’s design also takes into account ease of maintenance with features like throttle inserts for controlling pilot oil flow rates. Users are advised that internal leakage is an inherent feature of this type of valve but may increase over its lifecycle. The 4WEH series offers reliable performance in controlling hydraulic flows in various applications while ensuring durability and precision in operations.
