The Bosch Rexroth KUDSR3CA/FN9V (R901255657) is a high-precision proportional flow control valve designed for seamless integration into hydraulic systems requiring accurate flow modulation. This direct operated screw-in cartridge valve, featuring a spool design with an integrated pressure compensator, ensures that flow is continuously adjusted in proportion to the input signal. The valve's sophisticated structure comprises a robust housing, a responsive control spool, and a control spring, along with a pressure compensator piston, orifice bush, and pressure compensator spring. It is actuated by a proportional solenoid equipped with a central thread and detachable coil for easy maintenance and flexibility. With the ability to mount in a RUNF cavity, the KUDSR3CA/FN9V valve provides precise flow control in various applications. Its solenoid coil can be rotated for convenience during installation or system reconfiguration. Additionally, it offers the option of concealed manual override functionality for emergency or maintenance operations. For those requiring external access to manual override functions, there is an optional screwable star handle that can be installed. This Bosch Rexroth model is recognized for its robustness and reliability under maximum operating pressures and can handle significant flow rates efficiently. Its design ensures that any surplus residual flow is directed appropriately to the tank or another actuator via the port, maintaining optimal system performance without compromising on safety or efficiency. The KUDSR3CA/FN9V represents Bosch Rexroth's commitment to quality in hydraulic components, offering precise flow control solutions suitable for advanced hydraulic systems where accuracy and consistency are paramount.
