The Bosch Rexroth H-4WEH25X116-6X/6EG24N9ETK4/12B10D3 (R900965856) is a high-performance electrohydraulic directional control valve designed for subplate mounting with porting patterns that adhere to ISO standards. This model features a 4-way configuration and is equipped with wet-pin DC or AC solenoids, which can be optionally connected individually or centrally. It allows for either spring or pressure centering of the main control spool, with options for spring end position or hydraulic end position. The valve's main control spool is maintained in the zero position by pressure centering, ensuring reliable operation even when pilot pressure is not applied, such as in vertical valve positioning. The design includes return springs that secure the spool in the central position under depressurized conditions and with horizontal installation. However, these springs do not serve as return functions in this version. For flexibility in application, this valve offers various types of actuation through internal or external pilot control. The pilot oil supply can be executed either externally via channel X from a separate pressure source or internally from channel P of the main valve. Similarly, the pilot oil return can be managed externally to the tank via channel Y or internally through channel T. Additional customization options include manual override, switching time adjustment, a preload valve in channel P of the main valve, stroke setting, and spool position monitoring capabilities. It is important to note that any modification of the pilot oil supply should only be carried out by authorized specialists or at the factory to ensure proper functioning and adherence to maximum operating parameters. This Bosch Rexroth directional control valve stands out for its robust construction and versatility, making it suitable for various electrohydraulic applications where precise flow direction and fluid control are required.
