Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valves, designed with an innovative double plug and upper and lower guide structure. This versatile series is available in two types based on the flow path: the three-way diffluence valve, which features one inlet port and two outlet ports, and the three-way confluence valve, boasting two inlet ports and one outlet port. These valves are crafted to achieve fluid mixing for heating, cooling, and unequaled diffusion, perfectly tailored to meet diverse operational needs. This series is particularly ideal for fluid temperature regulation in heat exchangers, especially within the petroleum industry.

The AOC-6840 series comes equipped with a cutting-edge multi-spring pneumatic reinforced actuator. This feature allows for seamless on-site transformation between normally closed and normally open positions, significantly enhancing operational flexibility. Additionally, the actuator is ingeniously protected from corrosion, thus extending its service life and ensuring ease of use. The actuator's pipeless connection to the intelligent valve positioner boosts anti-corrosion performance, stability, and precision adjustment, empowering customers with exact control over varying working conditions.</sup>
