Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve is a sophisticated solution boasting a double plug, upper and lower guide structure. This series features two distinct types based on the path: the three-way diffluence valve, designed with one inlet port and two outlet ports, and the three-way confluence valve, featuring two inlet ports and a single outlet port. These configurations are expertly crafted to facilitate fluid mixing, heating, cooling, and unequal diffusing, fully catering to diverse operational requirements. This particular series is exceptionally adept at regulating fluid temperatures on heat exchangers, particularly within the petroleum industry, ensuring precise and reliable performance.

The AOC-6840 series features a multi-springs pneumatic reinforced actuator, which allows seamless on-site conversion between normally closed and normally open valve positions. The innovative design effectively shields the springs from corrosion, significantly extending the actuator's service life and enhancing operational convenience for customers. The actuator, paired with an intelligent valve positioner, is ingeniously connected without piping, bolstering anti-corrosion performance, stability, and precision adjustment. This ensures exact control over diverse working conditions, meeting the highest standards of operational excellence with ease.</sup>
