The Bosch Rexroth 4WEH 16 W1-7X/6EW110N9ETDA/B10 (R901253764) is a highly sophisticated electrohydraulic directional spool valve designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This model features a robust housing, main control spool, return springs, and a pilot control valve equipped with solenoids for precise actuation. The main control spool is maintained in the neutral position by the return springs or through pressurization, ensuring stability even with vertical valve positioning. The pilot control valve directs pilot oil to move the spool and thus change the connection between ports P with B and A with T. An optional manual override allows for manual operation in the absence of solenoid power. The WEH series valves are known for their reliability and are capable of internal or external pilot oil supply, with an inherent design that allows for internal leakage which may increase over time. This specific model includes various configurations for pilot oil supply and return, including external supply via channel X or internal supply from channel P of the main valve. For proper functioning, it incorporates throttle inserts to limit pilot oil flow when necessary. Additional features include optional versions such as manual override, switching time adjustment, preload valve in channel P of the main valve, stroke setting, and spool position monitoring. The Bosch Rexroth 4WEH 16 W1-7X/6EW110N9ETDA/B10 is designed for subplate mounting and conforms to ISO porting patterns. It offers flexibility in actuation methods—either spring or pressure centering—and is compatible with wet-pin DC or AC solenoids. Electrical connections can be made individually or centrally depending on system requirements. This directional valve is engineered to deliver precise hydraulic control across a range of applications without sacrificing performance or durability.
