The Bosch Rexroth 3FREEZ6B-1X/35L2G24K31F1MM (0811403152) is a state-of-the-art proportional flow control valve designed for precise fluid handling in hydraulic systems. These valves are engineered to facilitate direct operation with sizes 6 and 10, suitable for various applications where accurate flow regulation is essential. They are equipped with integrated electronics and an inductive position transducer that ensures position-controlled operation with minimal hysteresis, which is less than 1%. This high level of precision allows for consistent and reliable performance. These valves are specifically designed for subplate mounting and conform to the ISO 4401 porting pattern, making them versatile for integration into existing hydraulic systems. The innovative design includes a proportional solenoid that adjusts the valve position, responding to the feedback from the position transducer. This feedback loop results in rapid actuating times and finely tuned control over the hydraulic flow. The 3-way function of these valves is determined by the assignment of the hydraulic ports, with the residual current being channeled via port P. This feature enables efficient management of fluid flow within a system, ensuring that excess flow is redirected appropriately without causing disruptions or inefficiencies. Overall, the Bosch 3FREEZ6B-1X/35L2G24K31F1MM (0811403152) valves stand out due to their precision control capabilities, quick response times, and adaptability for subplate mounting in a wide range of hydraulic applications. Their robust design and integrated electronics make them a reliable choice for maintaining optimal flow conditions within complex machinery.
Proportional flow control valves of type 3FREEZ with position control and integrated electronics are offered in sizes 6 and 10. Operation is effected by means of a proportional solenoid with inductive position transducer. The hysteresis is <1 %. The installed electronics have been calibrated in the plant and allow for short actuating times. Due to the valve housing, the residual flow is guided via port P.
