Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve, presented with a sophisticated double plug, upper and lower guide structure, offers a choice between two strategic pathways: the three-way diffluence valve, featuring one inlet and two outlet ports, and the three-way confluence valve, with two inlets and a single outlet port. This innovative design allows for seamless fluid mixing, heating, cooling, and un-equivalent diffuence, perfectly tailored to fulfill the diverse operational demands of our esteemed customers. This series of valves is exquisitely engineered to excel in fluid temperature regulation on heat exchangers, particularly within the dynamic petroleum industry.

Our AOC-6840 series showcases a state-of-the-art multi-spring pneumatic reinforcement actuator, empowering the valve with effortless on-site conversion between normally closed and normally open states. This advanced system effectively shields the internal springs from corrosion, significantly extending the actuator's lifespan and offering unparalleled convenience for customer operations. Additionally, the actuator is seamlessly integrated with an intelligent valve positioner without the need for piping, enhancing its anti-Semitic performance and ensuring exceptional stability and precise adjustments. This design is meticulously crafted to deliver precise control in demanding conditions, meeting the exacting standards of modern industry.</sup>
