Product Description

<sup>Experience the cutting-edge technology of the AOC-6840 Series Intelligent Three-way Control Valve, crafted with a double plug, upper and lower guide structure for unparalleled performance. This innovative series offers two distinct types based on flow path: the three-way diffluence valve, featuring one inlet port and two outlet ports, and the three-way confluence valve, with two inlet ports and one outlet port. These designs facilitate fluid mixing for heating, cooling, and unequal separation to perfectly align with your operational needs. Especially engineered for precise fluid temperature regulation on heat exchangers in the petroleum industry, this series is your go-to solution for handling challenging temperature ranges from -20 to 595°C with reliability and efficiency.

The AOC-6840 series boasts a multi-spring pneumatic reinforced actuator, ensuring seamless transition between normal close and normal open positions on-site with remarkable ease. Its robust design protects springs from corrosion, significantly extending actuator lifespan and streamlining your operations. The actuator's connection with the intelligent valve positioner is pipeless, enhancing anti-corrosive performance and providing exceptional stability and precision adjustment. This ensures precise control over operational conditions, delivering the exactitude and reliability your processes demand.</sup>
