The Bosch Rexroth KUDSR3C2A/FN9V (R901265879) is a state-of-the-art proportional flow control valve, designed for precision management of fluid flow in hydraulic systems. This direct operated screw-in cartridge valve features a spool design with an integrated pressure compensator, ensuring that it controls the flow continuously and proportionally to the input signal. The valve is adept at handling any excessive residual flow by directing it either back to the tank or onto another actuator through its port. Constructed with a robust housing, the KUDSR3C2A/FN9V includes a control spool, control spring, and a pressure compensator piston. Additionally, it contains an orifice bush and pressure compensator spring that work together to maintain steady operation under varying pressures. The proportional solenoid of this valve comes with a central thread and is equipped with a detachable coil for ease of maintenance and flexibility in application. One of the key features of this model is its mounting cavity RUNF, which allows for straightforward installation. The actuation is performed by the proportional solenoid which can be rotated as needed for optimal positioning. Furthermore, this model offers a concealed manual override feature for additional control in manual operation scenarios. For those requiring an external manual override option, there is an optional screwable manual override available with a star handle design. This enhancement provides users with tactile feedback and precise control during adjustments. The KUDSR3C2A/FN9V has been designed to withstand maximum operating pressures up to bar levels and can facilitate flow rates up to max.lmin. Its compact size makes it suitable for various applications where space may be limited but precise flow control is essential. With its robust construction and advanced features, this Bosch Rexroth proportional flow control valve represents a reliable solution for managing fluid dynamics in sophisticated hydraulic systems.
The proportional flow control valve is a direct operated screw-in cartridge valve in spool design with integrated pressure compensator. It controls the flow continuously proportional to the input signal. Any excessive residual flow is led to the tank or to another actuator via the port.
The valve basically consists of housing, control spool, control spring, pressure compensator piston, orifice bush, pressure compensator spring as well as proportional solenoid with central thread and detachable coil.
