Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valves, designed with a sophisticated double plug and upper and lower guide structure. This innovative series offers two distinct types based on flow path: the three-way diffluence valve, with one inlet port leading to two outlet ports, and the three-way confluence valve, featuring two inlet ports converging to a single outlet port. These configurations are engineered to achieve precise fluid mixing, heating, cooling, and uneven distribution, perfectly catering to diverse operational requirements. Ideal for the petroleum industry's heat exchanger fluid temperature regulation, these valves ensure optimal performance in demanding environments.

The AOC-6840 series features a state-of-the-art multi-spring pneumatic reinforced actuator, enabling seamless on-site conversion between normally closed and normally open positions. This innovative design effectively shields the springs from corrosion, significantly extending the actuator's service life and simplifying user operations. Furthermore, the actuator is seamlessly connected to the intelligent valve positioner without piping, enhancing the valve's anti-static performance, stability, and precision adjustment capabilities. This ensures precise control over a variety of working conditions, delivering unmatched reliability and performance tailored to meet your exact needs.</sup>
