The Bosch Rexroth KUDSR3C1A/FN9V (R901287409) is a high-performance proportional flow control valve designed for precise fluid management in hydraulic systems. This direct-operated screw-in cartridge valve features an integrated pressure compensator and is capable of continuously adjusting the flow in proportion to an input signal. Its sophisticated design allows for the redirection of any excessive residual flow either back to the tank or towards another actuator via its port. Constructed with a robust housing, the valve incorporates a control spool, control spring, pressure compensator piston, orifice bush, and a pressure compensator spring. At the heart of its operation lies a proportional solenoid with a central thread that can be coupled with a detachable coil. The versatility of this model is further enhanced by the solenoid coil's ability to be rotated, ensuring ease of installation and maintenance. For manual control, the KUDSR3C1A/FN9V offers a concealed manual override feature. Additionally, there is an optional screwable manual override equipped with a star handle for situations where electronic actuation is not feasible or preferred. Designed to fit into mounting cavity RUNF, this direct operated proportional valve excels in controlling flow magnitudes with precision. The component series A of this model ensures compatibility with various applications and systems while maintaining maximum operating pressures up to bar levels and supporting maximum flow rates measured in liters per minute (l/min). Such specifications make it suitable for various hydraulic applications demanding reliable performance and precise control over fluid dynamics.
