'valve characteristics'


the effect of the double eccentric butterfly plate quickly after the valves are open from the seat, greatly eliminates the butterfly plate and valve seat of unnecessary and excessive squeeze scraping phenomenon;


and to reduce the resistance from the open, reduce the wear and tear, improve the working life of the seat.


the scrape the slash, double eccentric butterfly valve can be used in a metal seated, improves the application in the field of butterfly valves in high temperature.
