The Bosch Rexroth 3FREX6B-1X/35L2G24-25N9Z4MM (0811403113) is a proportional flow control valve designed for precision fluid management in hydraulic systems. This direct-operated valve is available in sizes 6 and 10, ensuring compatibility with various system requirements. It operates through a proportional solenoid which allows for smooth and accurate control of the flow rate, with an impressively low hysteresis of less than 5%. The valve's functionality can be adjusted by altering the solenoid current, providing users with fine-tuned control over their hydraulic operations. With its robust design, the valve is suitable for subplate mounting and adheres to the ISO 4401 porting pattern standard. It can be configured as either a 2-way or a 3-way flow control valve, depending on the hydraulic port assignments. In its 3-way configuration, residual flow is directed via port P, while in the 2-way setup, it operates with A to B flow dynamics with ports P and T being closed. The model's versatility is further highlighted by its two operational symbols: "NO" (normally open) and "NC" (normally closed). The "NO" configuration restricts it to function solely as a 2-way flow control valve, whereas the "NC" allows it to serve as either a 3-way or a 2-way valve. This flexibility makes it an essential component for various applications where precise fluid regulation is critical. Overall, this Bosch proportional flow control valve stands out for its precise operation, adaptability to different system configurations, and compliance with industry standards. Its sophisticated design ensures reliable performance in controlling fluid dynamics within hydraulic systems.
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).
