The Bosch Rexroth 4WEH 10 EA4X/6EW110N9ETS2K4 (R900930055) is a highly sophisticated directional spool valve with electrohydraulic actuation, designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This model is engineered for subplate mounting and conforms to ISO porting patterns. It is available in 3 or 4-way versions with options for spring or pressure centering and spring end position or hydraulic end position. The valve features wet-pin DC or AC solenoids which can be connected either individually or through a central connection. The valve's main control spool is maintained in the neutral position by return springs or pressurization, ensuring reliable operation even in vertical installations. An optional manual override provides flexibility by allowing manual operation of the pilot control spool without solenoid activation. For tailored performance, this model includes options such as switching time adjustment, a preload valve in channel P of the main valve, stroke setting, and spool position monitoring. The design accommodates both internal and external pilot oil supplies and returns. The internal version (ET and E) sources pilot oil from channel P of the main valve, while external versions utilize separate pressure supplies via channel X. The return of pilot oil can be managed internally through channel T or externally through channel Y depending on the configuration. To ensure precise control over pilot oil flow, a throttle insert may be utilized if necessary to limit supply in channel P of the pilot control valve. However, modifications to the pilot oil supply should only be executed by authorized specialists to maintain system integrity and performance. This Bosch Rexroth directional valve integrates seamlessly into advanced hydraulic systems requiring robust control solutions with customizable features for optimized operation across various applications.
