centerline butterfly valves

Centerline butterfly valve is a component used to realize the on-off and flow control of the pipeline system. The structure of the centerline butterfly valve is that the stem axis, the disc center, and the body center are in the same position. It has been used in petroleum, chemical, metallurgy, hydropower It has been widely used in many fields, its sealing mostly adopts the sealing structure with the materials in rubber, polytetrafluoroethylene, etc. Due to the structural limitation, it cannot withstand high temperature and high pressure, and not resistant to corrosion and wear.

advantage：

The structure is simple and the manufacture is convenient.

shortcoming：

Because the valve plate and valve seat are always in a state of extrusion and scraping, the resistance distance is large and the wear is fast.

In order to overcome extrusion, scratching and ensure sealing performance, the valve seat of the centerline butterfly valve is basically made of elastic materials such as rubber or PTFE, but due to the characteristics of the sealing material, its use is limited by temperature, which is why It is traditionally believed that butterfly valves are not resistant to high temperatures.
