Product Description

<sup>Introducing the AOC-6840 Series Intelligent Three-way Control Valve, a marvel of engineering that combines a double plug with an upper and lower guide structure for optimal fluid management. Designed to perfection, this valve comes in two versatile types: 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 empower you to achieve precise fluid mixing, heating, cooling, and a unique diffusion capability, tailored to meet diverse operational requirements. This series of valves is exceptionally suited for regulating fluid temperatures in the heat exchangers of the petroleum industry, ensuring seamless performance and reliability.

The AOC-6840 series comes equipped with a state-of-the-art multi-springs pneumatic reinforcement actuator, which facilitates effortless conversion between normally closed and normally open positions on-site, providing unparalleled flexibility. The innovative design effectively shields the springs from corrosion, significantly prolonging the actuator's service life and enhancing user convenience. Moreover, the actuator seamlessly integrates with the intelligent valve positioner in a pipeless connection, bolstering anti-corrosion performance, stability, and precision adjustment. This ensures exceptional control over working conditions, meeting exacting standards of performance and reliability.</sup>
