Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valve, a marvel of engineering that features a sophisticated double plug, upper, and lower guide structure. This series offers two distinct configurations: the three-way diffluence valve with one inlet port and two outlet ports, and the three-way confluence valve with two inlet ports and one outlet port. This flexibility allows for precise fluid mixing, heating, cooling, and differentiated flow, perfectly aligning with your operational needs. These valves are particularly ideal for the meticulous regulation of fluid temperature in heat exchangers within the petroleum industry, guaranteeing optimal performance and reliability.

The AOC-6840 series is equipped with a multi-springs pneumatic reinforced actuator, which facilitates effortless on-site conversion between normally closed and normally open positions. This design effectively shields the spring from corrosive elements, thereby extending the actuator's lifespan and enhancing operational convenience for customers. Furthermore, the actuator is seamlessly integrated with an intelligent valve positioner without the need for pipes, bolstering anti-corrosive performance, stability, and precision adjustment. This ensures meticulous control over working conditions, delivering consistent and precise performance tailored to your exact specifications.</sup>
