Product Description

<sup>The AOC-6840 Series of Intelligent Three-way Control Valve is a masterpiece of engineering, featuring a sophisticated double plug with an upper and lower guide structure. This cutting-edge valve is available in two configurations: the three-way diffluence valve, which boasts one inlet port and two outlet ports, and the three-way confluence valve, designed with two inlet ports and one outlet port. These configurations enable precise fluid mixing, heating, cooling, and unequaled diffuence to meticulously align with the diverse operational demands of our esteemed clientele. Particularly adept at fluid temperature regulation, this series is an ideal solution for heat exchangers within the petroleum industry, offering unrivaled efficiency and performance.

The AOC-6840 Series features a sophisticated multi-springs pneumatic reinforce actuator, expertly designed to facilitate seamless conversion between normally closed and normally open states effortlessly. This design innovation ensures the spring components are effectively shielded from corrosion, significantly extending the actuator's service life and enhancing ease of use for our valued customers. The actuator is complemented by an advanced pipeless connection to the intelligent valve positioner, delivering enhanced anti-seismic performance, exceptional stability, and precision adjustment capabilities. This integration ensures unparalleled control and adaptability, perfectly tailored to meet the exacting demands of various working conditions.</sup>
