The Bosch Rexroth 4WEH16D7X/OF6EW110N9ESK4 CSA (R978009106) is a high-performance directional control valve designed for electrohydraulic actuation, providing precise control over the start, stop, and direction of fluid flow in hydraulic systems. The valve is characterized by its robust construction which includes a main valve with housing, a main control spool, return springs, and a pilot control valve equipped with solenoids for operation. This sophisticated piece of hydraulic equipment is engineered to maintain the main control spool in its central position by default, either through spring force or via pressure centering depending on the specific type of WEH valve. The pilot control valve ensures that upon electrical actuation, pilot pressure is directed to move the main control spool against the return springs, allowing for an efficient change in flow direction between ports. The internal design allows for leakage which may naturally increase over time due to wear and tear. The model offers flexibility in terms of pilot oil supply and return configurations; it can be set up with either internal or external pilot oil supply routes depending on the application needs. Furthermore, this model features an optional manual override capability which provides additional operational security by enabling manual actuation in case of electrical power failure. In terms of customization and adaptability, this Bosch Rexroth directional valve can be tailored to specific system requirements. It supports various types of actuation such as electrohydraulic operation and can be mounted on subplates with porting patterns compliant with ISO standards. The unit can be configured as a 3-way or 4-way version with options for spring or pressure centering and comes equipped with wet-pin DC or AC solenoids that offer reliable performance. Additional optional features include switching time adjustment mechanisms, preload valves in channel P of the main valve for enhanced stability during operation, stroke setting adjustments, and spool position monitoring capabilities. These options provide greater control over hydraulic system behavior and allow for fine-tuning to meet precise application demands.
