Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valve, a marvel of engineering excellence. This state-of-the-art valve boasts a double plug and upper and lower guide structure, designed to elevate your fluid handling operations. Available in two sophisticated types-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 series caters to a myriad of fluid dynamics needs. Achieve unparalleled fluid mixing, heating, cooling, and non-equivalent diffusion to meet even the most demanding operational requirements. Tailored specifically for the intricate temperature regulation on heat exchangers within the petroleum industry, the AOC-6840 Series delivers unmatched performance and reliability.

The AOC-6840 Series features a cutting-edge multi-springs pneumatic reinforce actuator, seamlessly facilitating on-site conversions between normally closed and normally open positions. This innovative design ensures that the springs are effectively shielded from corrosion, significantly extending the actuator's lifespan and simplifying customer operations. With a pipeless connection between the actuator and the intelligent valve positioner, the system offers superior anti-Semitic performance, stability, and precision adjustment. This robust configuration enables precise control over working conditions, ensuring that your operations run smoothly and efficiently, meeting exacting standards of performance and reliability.</sup>
