The Bosch Rexroth 4WEH10J4X/6EG24N9ETS2DK24L (R978909327) is a high-performance directional spool valve with electrohydraulic actuation designed for controlling the start, stop, and direction of fluid flow. This model is engineered for subplate mounting and adheres to ISO porting patterns. It is configurable as a 3- or 4-way version and features options for spring or pressure centering, as well as spring end position or hydraulic end position control. The main valve includes a housing, control spool, return springs, and pilot control valve with solenoids that facilitate the manipulation of fluid dynamics within hydraulic systems. The device also offers wet-pin DC or AC solenoids with optional electrical connections that can be configured either individually or centrally. For enhanced operational flexibility, this model provides various optional features such as manual override capabilities, switching time adjustments, a preload valve in channel P of the main valve, stroke setting, and spool position monitoring. This Bosch Rexroth valve is particularly suitable for applications requiring precise control over hydraulic flow with the reliability of electrohydraulic actuation. It has been designed to maintain its central position via return springs or pressurization even when installed vertically. Although internal leakage is an inherent characteristic due to its design principle and may increase over time, this does not detract from its overall effectiveness in industrial applications. The 4WEH10J4X/6EG24N9ETS2DK24L offers flexibility in pilot oil supply and return configurations – it can be set up for external supply via channel X or internal supply depending on the specific model variant. The pilot oil return can also be configured either externally through channel Y into the tank or internally via channel T. This allows users to tailor the valve's operation to suit various system requirements while ensuring optimal performance and reliability in controlling hydraulic flow within their machinery.
