The Bosch Rexroth 4WEH 32 H6X/6EW110N9EK4 (R900931184) is a high-performance directional valve designed for electrohydraulic actuation. This directional spool valve is essential for controlling the start, stop, and direction of fluid flow in hydraulic systems. It is comprised of a main valve with housing, a control spool, return springs, and a pilot control valve with solenoids for operation. The main control spool can be maintained in its initial position either by the return springs or through pressurization. The valve offers various pilot oil supply options including internal and external via port X, as well as pilot oil return internally through channel T or externally through channel Y. An optional manual override feature allows for manual operation of the pilot control spool without solenoid activation. The WEH series valves are designed to be mounted on subplates with porting patterns that conform to ISO standards and are available in 3- or 4-way versions. These valves can be customized with features such as spring or pressure centering, spring end position or hydraulic end position configurations. The solenoids used for actuation can be either wet-pin DC or AC types and come with options for individual or central electrical connections. Additional customization options include manual overrides, switching time adjustments, preload valves in channel P of the main valve, stroke setting, and spool position monitoring. The Bosch Rexroth 4WEH series valves are engineered to accommodate internal leakage which is inherent to their design but may increase over the life cycle due to wear and tear. It's important to note that any modifications to the pilot oil supply should only be performed by authorized specialists or at the factory to ensure proper functioning and safety of the system.
