Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valves is engineered with a sophisticated double plug and upper and lower guide structure. This innovative series is available in two distinct types based on flow path: the three-way diffluence valve, equipped with one inlet port and two outlet ports, and the three-way confluence valve, featuring two inlet ports and one outlet port. These configurations are meticulously designed to achieve precise fluid mixing, heating, cooling, and variable diffusion to perfectly align with the operational demands of our valued customers. This exceptional series of valves is specifically tailored for the petroleum industry's heat exchanger fluid temperature regulation, ensuring unmatched performance and reliability.

The AOC-6840 Series introduces the advanced multi-springs pneumatic reinforced actuator, which effortlessly facilitates on-site conversion between normally closed and normally open positions. This actuator effectively shields the spring from corrosive elements, significantly extending its service life and enhancing user convenience. The actuator seamlessly connects with the intelligent valve positioner without the need for piping, enhancing resistance to environmental factors while ensuring superior stability and precision. This innovation delivers exceptional control over working conditions, meeting the demands of exacting performance and operational precision.</sup>
