Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valve, a remarkable innovation featuring a double plug and upper and lower guide structure. This series is engineered to perfection, offering two distinct types based on the flow path: the three-way diffluence valve, designed with one inlet port and two outlet ports, and the three-way confluence valve, crafted with two inlet ports and one outlet port. These versatile configurations enable precise fluid mixing for heating, cooling, and unequal diffuence, catering to a diverse range of operational requirements with unparalleled efficiency. This sophisticated valve series is particularly adept at managing fluid temperature regulation in the heat exchangers of the petroleum industry, delivering exceptional performance and reliability.

The AOC-6840 series boasts a multi-springs pneumatic reinforced actuator, revolutionizing valve operation by facilitating seamless transitions between normally closed and normally open positions on-site. This feature ensures the springs are effectively shielded from corrosion, significantly extending the actuator's service life and enhancing ease of use for our customers. Additionally, the actuator is ingeniously connected to the intelligent valve positioner without the use of pipes, enhancing its anti-corrosive properties, stability, and precision in adjustment. This design ensures precise control over operational conditions, making the AOC-6840 series an indispensable asset for demanding industrial environments.</sup>
