  High Performance Butterfly Valve

        

Product Description

• Triple eccentric butterfly valve can meet the requirements of high temperature, high pressure abnd strong corrosion, high wear and other working conditions, with light weight, compact structure, low operating torque,etc. can replace the conventional gate valve, globe valve and ball valve under most conditions.

• High performance butterfly valve is a new type of butterfly valve designed based on the advantages of absorbing several different structural butterfly valves.

• The valve plate sealing surface of this butterfly valve is a ball arc body, and the sealing mechanism achieves a true dynamic seal through the syetem pressure, so it has excellent cutting performance and durability performance. Its small size, light weight, a wide range of manufacturing, easy maintenance.

  
  

Features 

• The sealing performance is good and the reliability of the system is improved.

• Small frictional resistance, open and close effort, flexibility. 

• Long service life，can achieve repeated switching.

• High pressure and high temperature resistance, wide application range.
