The Bosch Rexroth 4WEH16L8-7X/6EG24N9EK4/B10 (R901017115) is a high-performance directional control valve designed for managing the flow and direction of hydraulic fluid in complex systems. This electrohydraulically operated valve is part of the WEH series, characterized by its versatility and reliability in controlling start, stop, and directional operations of fluid flow. The model features a main valve with housing, a control spool, return springs, and a pilot control valve equipped with solenoids for precise actuation. The main control spool is maintained in its neutral position either by the return springs or through pressurization. The actuation process involves moving the pilot control spool via solenoid engagement, which pressurizes one chamber while depressurizing the other to shift the main spool and alter the connection between ports. This action allows for smooth transitioning between different states such as connecting port P with B and A with T. An optional manual override is available to manually adjust the pilot control spool without needing to energize the solenoids. Additionally, this model offers flexibility in terms of pilot oil supply and return configurations, including external supply via port X or internal options that utilize channels within the valve itself. The Bosch Rexroth 4WEH16L8-7X/6EG24N9EK4/B10 valve supports various types of actuation—internal or external pilot control—and can be mounted on a subplate with porting patterns following ISO standards. It can be used in both 3-way and 4-way versions and provides options for spring or pressure centering as well as spring end positioning or hydraulic end positioning. The wet-pin DC or AC solenoids are designed for robust performance even under demanding conditions. Other notable features include electrical connection options that cater to both individual wiring or central connections, manual override capabilities for direct intervention in system operation, switching time adjustments for fine-tuning system dynamics, preload valves in channel P of the main valve for enhanced stability during operation, stroke setting adjustments, and spool position monitoring to ensure optimal performance throughout its service life.
