Application

As a kind of component used to realize the on-off and flow control of pipeline system, butterfly valve has been widely used in many fields such as petroleum, chemical, metallurgy, hydropower and so on. In the well-known butterfly valve technology, the sealing form is mostly sealed, and the sealing material is rubber, polytetrafluoroethylene or the like. Due to structural limitations, it is not suitable for industries such as high temperature resistance, high pressure, corrosion resistance and wear resistance.

Feature

The butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switch, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline. Fluid control characteristics and shut-off sealing performance.
