Product Description

<sup>Discover the AOC-6840 Series of Intelligent Three-way Control Valves, engineered with a double plug and upper and lower guide structure. This innovative series offers two versatile types: the 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. These designs are meticulously crafted to facilitate fluid mixing, heating, cooling, and un-equivalent diffuence, all tailored to meet your precise operational needs. Perfectly suited for fluid temperature regulation on heat exchangers within the petroleum industry, this series guarantees superior performance and reliability.

Introducing the AOC-6840 Series multi-springs pneumatic reinforce actuator, a marvel of modern engineering. This actuator empowers the valve to seamlessly convert between normally closed and normally open states on-site, enhancing operational flexibility. The innovative design effectively shields the spring from corrosion, significantly extending the actuator's service life and enhancing user convenience. With a pipeless connection between the actuator and the intelligent valve positioner, this system bolsters anti-interference performance, stability, and precision adjustment. It ensures accurate control over working conditions, aligning perfectly with your exacting standards.</sup>
