The Bosch Rexroth 2FREX10B-1X/70L1G24-25N9Z4MM (0811403013) is a state-of-the-art proportional flow control valve designed for precision hydraulic applications. This direct operated valve comes in sizes 6 and 10, ensuring compatibility with various system requirements. It operates through a proportional solenoid that guarantees responsiveness and accuracy, with a hysteresis of less than 5%, which speaks to its high degree of control fidelity. The valve's design allows for different configurations: it can function as a 2-way flow control valve when using the "NO" (normally open) symbol, or as a 3-way or 2-way flow control valve with the "NC" (normally closed) symbol. In the 3-way configuration, residual flow is directed via port P, while in the 2-way setup, ports A to B are utilized with ports P and T being closed. This model is particularly versatile due to its adjustable nature via solenoid current, allowing users to fine-tune their hydraulic systems for optimal performance. The Bosch Rexroth 2FREX10B-1X/70L1G24-25N9Z4MM is designed for subplate mounting and adheres to the ISO 4401 porting pattern standard, ensuring ease of installation and maintenance. Its robust construction and flexible operation make it suitable for a wide range of applications requiring precise fluid control 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).
