Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve offers an advanced engineering marvel with its double plug, upper and lower guide structure. This series is expertly crafted in two distinct configurations: the three-way diffluence valve, featuring a single inlet port and dual outlet ports, and the three-way confluence valve, designed with dual inlet ports converging into a single outlet port. These configurations enable precise fluid mixing, heating, cooling, and differential flow distribution to meticulously align with customer-specific operational requirements. Ideal for the petroleum industry, these valves are exceptionally well-suited for regulating fluid temperature in heat exchangers.

The AOC-6840 series introduces a multi-springs pneumatic reinforced actuator that effortlessly empowers the valve to transition between normally closed and normally open states with ease. This innovation ensures the spring is effectively shielded from corrosion, significantly extending the actuator's lifespan and simplifying user operations. The actuator's seamless integration with the intelligent valve positioner, without the need for piping, enhances its anti-corrosive capabilities, stability, and precision adjustment. This thoughtful design guarantees precise control over working conditions, meeting the highest standards of operational performance.</sup>
