Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve stands out with its innovative double plug, upper, and lower guide structure. Crafted for versatility, these valves offer two distinct 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 and one outlet port. This configuration allows precise fluid mixing, heating, cooling, and unequal diffluence, tailored to meet diverse operational requirements. Perfectly engineered for the petroleum industry, this series excels in fluid temperature regulation on heat exchangers, ensuring optimal performance and satisfaction for our discerning customers.

The AOC-6840 series features a multi-spring pneumatic reinforce actuator, streamlining the on-site conversion between normally closed and normally open states with ease. This actuator is ingeniously designed to shield the springs from corrosion, thereby significantly extending its service life while enhancing user convenience. The actuator pairs seamlessly with the intelligent valve positioner, utilizing a pipeless connection to boost anti-seismic performance, stability, and precision. This advanced design ensures exact control of operational conditions, meeting the highest standards of accuracy and reliability for our valued customers.</sup>
