The Bosch Rexroth 4WEH22X104-7X/6EG24N9DK25L (R900925905) is a high-performance directional spool valve with electrohydraulic actuation, designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This model features a main valve with housing, a control spool, return springs, and a pilot control valve equipped with solenoids for precise operation. The main control spool is maintained in the central position by the springs or through pressurization when in the initial state. The valve's operation involves shifting the main control spool via pilot pressure which is directed through the pilot control valve. This action connects or disconnects ports within the main valve to regulate fluid flow. An optional manual override feature is included to allow movement of the pilot control spool without solenoid energization. This Bosch Rexroth directional valve offers versatility with various options for pilot oil supply and return paths, including internal and external configurations. It can be mounted on a subplate and conforms to ISO porting patterns. The model provides flexibility in terms of actuation types—either spring or pressure centering—and end positions that can be spring-based or hydraulically defined. Additional features such as wet-pin DC or AC solenoids cater to different electrical requirements, while optional versions offer manual overrides, switching time adjustments, preload valves in channel P of the main valve, stroke setting, and spool position monitoring. These characteristics ensure that the 4WEH22X104-7X/6EG24N9DK25L can be tailored to meet specific application needs while maintaining reliable performance and precision flow control within hydraulic systems.
