Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve by SNT Machinery (Qingdao) Co., Ltd. is a pinnacle of advanced engineering, equipped with a double plug, upper and lower guide structure. This sophisticated line offers two types based on flow paths: the three-way diffluence valve, which features one inlet port and two outlet ports, and the three-way confluence valve, with two inlet ports and one outlet port. These versatile configurations are expertly crafted to facilitate fluid mixing, heating, cooling, and unequal diffusion, perfectly aligning with diverse operational requirements. This series is ideally suited for precise fluid temperature regulation in the heat exchangers of the petroleum industry, ensuring optimal performance and reliability.

The AOC-6840 series, featuring a multi-springs pneumatic reinforce actuator, empowers seamless on-site conversion between normally closed and normally open positions. This state-of-the-art design effectively shields the spring from corrosion, thereby extending the actuator's service life while simplifying customer operations. Moreover, the actuator is ingeniously integrated with the intelligent valve positioner through a pipeless connection, enhancing anti-Semitic performance, stability, and precision adjustment. This ensures an unparalleled level of control to meet exacting working conditions, delivering excellence and precision in every application.</sup>
