New structure Butterfly advantages and disadvantages

At present, the butterfly valve as a piping system off and flow control components used to achieve in petroleum,
To be very widely used in the chemical industry, metallurgy, water and electricity in many areas. In known butterfly art,
The seal forms enclosed structure, sealing materials such as rubber, PTFE. As the structural characteristics.

Limit is not suitable for high temperature, high pressure and corrosion resistance, abrasion resistance and other industries.
Present a more advanced butterfly valve triple eccentric metal seal butterfly valve, valve and valve seat for Siamese components
Seat sealing surface layer welding temperature, corrosion resistant alloys. The multi-layer soft stacked ring is fixed to the valve plate,
With the transmission of this butterfly valve in comparison with a high temperature, easy operation, open and close without friction Close
The torque increases to compensate for seal, a butterfly valve sealing performance and durability advantages.
