Product Description

<sup>Introducing the remarkable AOC-6840 Series of Intelligent Three-way Control Valves, designed with an advanced double plug and upper and lower guide structure. These innovative valves are available in two types based on fluid path configuration: the three-way diffluence valve, featuring one inlet port and two outlet ports, ideal for channeling fluid into multiple flows; and the three-way confluence valve, equipped with two inlet ports and one outlet port, perfect for fluid mixing processes. Engineered to perfection, these valves are adept at facilitating fluid mixing, heating, cooling, and un-equivalent diffluence to seamlessly cater to diverse operational requirements. Our AOC-6840 Series is particularly well-suited for precise fluid temperature regulation within heat exchangers in the petroleum industry, ensuring optimal performance and reliability.

The AOC-6840 series boasts a state-of-the-art multi-springs pneumatic reinforced actuator, empowering the valve to effortlessly switch between normally closed and normally open positions on-site. This ingenious mechanism effectively protects the springs from corrosion, significantly extending the actuator's service life while ensuring hassle-free operation for our customers. Furthermore, the actuator is seamlessly integrated with the intelligent valve positioner without the need for pipelines, enhancing anti-corrosion resilience, stability, and precision in adjustments. This meticulous setup guarantees precise control over various working conditions, achieving exemplary performance that meets exacting industry standards.</sup>
