Discover Innovative High-Temperature Resistant Butterfly Valves

The centerlineline butterfly valve is a type of butterfly valve known for its simple and easy-to-manufacture structure. In this type of valve, the valve stem , disc at centerline, and body at centerline, are all located at the same position. This design feature makes it a common choice for rubber-lined butterfly valves.
 
However, the structural feature of the centerline butterfly valve also comes with its drawbacks. One major disadvantage is that the disc and valve seat are constantly in a state of extrusion and scraping, leading to high resistance and rapid wear. To address this issue and ensure sealing performance, the valve seat is typically made of elastic materials such as rubber or polytetrafluoroethylene. While this helps to overcome extrusion and scratching, it also imposes temperature limitations on the valve’s use.
 
As a result, there is a traditional belief that butterfly valves, especially those with rubber seats, are not resistant to high temperatures. The use of elastic materials in the valve seat construction limits the maximum temperature at which the valve can operate effectively. This drawback has led many to view butterfly valves as unsuitable for applications involving high temperatures.

Despite this traditional belief, advancements in materials and design have led to the development of high-temperature resistant butterfly valves. Engineers and manufacturers have been able to overcome the limitations of traditional centerline butterfly valves by utilizing new materials and innovative designs. These advancements have expanded the applications of butterfly valves to include high-temperature environments, challenging the long-held belief about their temperature resistance.

In conclusion, while the structural features of centerline butterfly valves may have initially limited their use in high-temperature applications, ongoing advancements in materials and design have expanded their capabilities. With the development of high-temperature resistant butterfly valves, the traditional view of butterfly valves as unsuitable for high-temperature environments is being challenged.
