Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valves, designed with a sophisticated double plug and upper and lower guide structure. This innovative series offers two distinct types based on fluid path: the three-way diffluence valve, featuring one inlet port and two outlet ports, and the three-way confluence valve, with two inlet ports and one outlet port. These configurations adeptly manage fluid mixing, heating, cooling, and unequal distribution, perfectly tailored to meet operational requirements. Ideal for the petroleum industry, these valves are particularly suited for precise fluid temperature regulation on heat exchangers, ensuring optimal performance and reliability.

The AOC-6840 series boasts a state-of-the-art multi-spring pneumatic reinforced actuator, enhancing user convenience by facilitating seamless on-site conversions between normally closed and normally open states. This advanced design effectively shields the springs from corrosion, significantly extending the actuator's service life and simplifying operational processes. The actuator's synergy with the intelligent valve positioner, connected without piping, elevates anti-corrosive performance, stability, and adjustment precision. This ensures exceptional control over diverse working conditions, meeting even the most exacting specifications with remarkable accuracy and reliability.</sup>
