Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve is engineered with a double plug and features an upper and lower guide structure. It offers two versatile configurations: the three-way diffluence valve, equipped with one inlet port and two outlet ports, and the three-way confluence valve, boasting two inlet ports and one outlet port. This design facilitates seamless fluid mixing, heating, cooling, and adaptable diffusing functionalities, thereby catering to diverse operational needs. Tailored specifically for the petroleum industry, this series excels in regulating fluid temperature on heat exchangers, ensuring optimal performance and reliability for our esteemed customers.

The AOC-6840 series is enhanced by a multi-springs pneumatic reinforce actuator, allowing for effortless on-site conversion between normal close and normal open positions. The actuator's design effectively safeguards the springs from corrosive damage, significantly extending actuator longevity and ensuring smooth operation for our customers. The actuator's innovative pipeless connection to the intelligent valve positioner enhances its anti-seismic capabilities, providing remarkable stability and precision. This integration ensures exact control over diverse working conditions, meeting the highest standards of performance and reliability.</sup>
