Wafer Type Triple Offset Butterfly Valve
Wafer type triple offset butterfly valve has the advantage of being resistant to high temperatures, high pressure and corrosion. It is a hard seal butterfly valve, usually suitable for high temperature（≤425℃）, and the Maximum pressure can be 63bar. The structure of the wafer type triple eccentric butterfly valve is shorter than the flang triple eccentric butterfly valve, so the price is cheaper.
