Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valves, a pinnacle of engineering featuring a sophisticated double plug design and an advanced upper and lower guide structure. This series seamlessly adapts to fluid management needs with its dual configurations: the three-way diffluence valve, offering one inlet port and two outlet ports, and the three-way confluence valve, with two inlet ports converging into one outlet port. These valves are meticulously crafted to fulfill a spectrum of fluid mixing, heating, cooling, and differential flow requirements, tailored to meet any operational demand. Perfectly suited for precise fluid temperature regulation, they are indispensable in the heat exchangers of the petroleum industry, ensuring unparalleled efficiency and reliability.

The AOC-6840 series features a state-of-the-art multi-spring pneumatic reinforced actuator, designed to facilitate a seamless transition between normally closed and open states with remarkable ease on-site. This intelligent design effectively shields the spring from corrosive elements, significantly extending the actuator's lifespan while enhancing operational convenience for users. The actuator pairs innovatively with a pipeless intelligent valve positioner, boosting its anti-seismic capabilities, stability, and precision. This cutting-edge integration ensures the utmost control over operating conditions, delivering exceptional performance and accuracy in every application.</sup>
