Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valves, designed with an advanced double plug and upper-lower guide structure. This series offers two versatile types based on flow paths: the three-way diffluence valve, featuring one inlet port and two outlet ports, and the three-way confluence valve, with two inlet ports converging into a single outlet. These configurations are meticulously crafted to facilitate fluid mixing, heating, cooling, and differential distribution, ensuring alignment with diverse operational demands. Engineered specifically for the petroleum industry, these valves excel in fluid temperature regulation within heat exchangers, offering unparalleled precision and performance.

The AOC-6840 series boasts a cutting-edge multi-spring pneumatic reinforced actuator, which enables seamless on-site conversion between normally closed and normally open states, enhancing user convenience. This actuator is intelligently designed to shield the spring from corrosive elements, significantly extending its operational lifespan. Furthermore, the actuator is seamlessly integrated with an intelligent valve positioner without the need for cumbersome piping, thereby enhancing its anti-seismic properties, stability, and precision adjustment capabilities. This integration ensures that the valves deliver precise control tailored to specific working conditions, meeting and exceeding customer expectations.</sup>
