3.Features of high temperature butterfly valve:

When the high temperature butterfly valve is in the closed position, there is a gap between the valve plate and the valve body to ensure that it can still be used normally during thermal expansion. Because the high temperature butterfly valve is specially used for exhaust gas of industrial furnace system to achieve automatic control and regulation of furnace pressure, it is also called flue butterfly valve.
