The Bosch Rexroth 4WEH 16 JB7X/6EG24N9ETK4 (R900929239) is a highly sophisticated directional spool valve designed for electrohydraulic actuation, enabling precise control over the start, stop, and direction of fluid flow. This valve features a robust housing and includes a main control spool, return springs, and a pilot control valve with solenoids for operation. The main control spool can be held in its initial position either by the return springs or through pressurization. When the pilot control valve is activated by one of its solenoids, the resulting pilot pressure shifts the main control spool against the opposing spring force, allowing for fluid connectivity between specified ports in the main valve. Upon deactivation of the solenoid, internal mechanisms allow for a return to the neutral position. An optional manual override is available for manual actuation without energizing the solenoid. This model includes an internal leakage design that may increase over its lifecycle due to its operational principle. The WEH series valves offer options such as pressure centering of the main control spool and various configurations for pilot oil supply and return—either internally from channel P or externally via channels X or Y—depending on specific model types (WEH...ET..., WEH...T..., etc.). The throttle insert feature allows for regulation of pilot oil supply if necessary. The 4WEH 16 JB7X/6EG24N9ETK4 is designed for subplate mounting with porting patterns conforming to ISO standards. It can be configured as a 3- or 4-way version with options such as spring or pressure centering and spring end position or hydraulic end position. Solenoids are available in wet-pin DC or AC versions with electrical connections tailored to individual or central connection requirements. Additional customization options include manual overrides, switching time adjustments, preload valves in channel P of the main valve, stroke setting, and spool position monitoring. This versatility ensures that this directional valve can meet various application requirements while maintaining precise fluid control within hydraulic systems.
