The Bosch Rexroth 2FREX6B-1X/35L1G24-25N9Z4MM-254 (0811403119) is a direct operated proportional flow control valve designed for precision management of fluid flow within hydraulic systems. This model, suitable for subplate mounting, adheres to the porting pattern outlined by ISO 4401 standards, ensuring compatibility and ease of integration into various hydraulic circuits. It operates as a 3(2)FREX valve without position control and is available in sizes 6 and 10. The valve's operation is governed by a proportional solenoid, which allows for adjustable flow control based on the solenoid current. This flexibility makes it an ideal component for applications requiring precise modulation of flow rates. The hysteresis of this model is less than 5%, highlighting its ability to maintain consistent performance and reduce variability in the controlled flow. Depending on the configuration of its hydraulic ports, the valve can function as either a 2-way or 3-way control valve. In its 'NO' (normally open) configuration, it operates exclusively as a 2-way flow control valve, with ports P and T closed when in the neutral position. Conversely, the 'NC' (normally closed) configuration allows it to be used as both a 3-way or a 2-way flow control valve, with residual flow being directed through port P in the 3-way version. The versatility provided by these operational modes enables users to tailor the valve's function to match specific application requirements. The robust design and manufacturing quality of this Bosch proportional flow control valve ensure reliability and longevity in demanding operational environments.
Proportional flow control valves of type 3(2)FREX without position control are offered in sizes 6 and 10. Operation is effected by means of proportional solenoid. The hysteresis is < 5 %. The valve amplifier electronics are available in different designs. The “NO” (normally open) symbol can only be used as 2-way flow control valve (type 2FREX). The “NC” (normally closed” symbol can be used as 3-way or 2-way flow control valve. Due to the valve housing, the residual flow in the 3-way version is guided via port P. For the 2-way version, the following is true: A to B (P and T are closed).
