Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve is engineered with a sophisticated double plug design, utilizing an upper and lower guide structure for enhanced performance. Depending on the flow path, these valves are available in two configurations: the three-way diffluence valve, which features one inlet port and two outlet ports, and the three-way confluence valve, with two inlet ports and one outlet port. These designs enable precise fluid mixing for heating, cooling, and un-equivalent diffuence, perfectly tailored to meet diverse operational requirements. This versatile series is exceptionally suited for fluid temperature regulation on heat exchangers, particularly within the petroleum industry, ensuring optimal efficiency and reliability.

The AOC-6840 series boasts a state-of-the-art multi-springs pneumatic reinforce actuator, facilitating seamless on-site conversion between normally closed and normally open states. This innovative actuator design extends the service life by effectively shielding its springs from corrosive elements, thereby ensuring longevity and ease of operation for customers. Furthermore, the actuator's integration with the intelligent valve positioner is achieved without the need for piping, enhancing its anti-corrosive properties. This pipeless connection ensures superior stability and precision adjustment, delivering exact control over working conditions and performance, which is especially crucial in demanding environments.</sup>
