In petroleum, petrochemical, chemical, electric power, and urban construction, metal-to-metal sealing ball valves can be selected for pipeline systems
The triple eccentric butterfly valve usually adopts metal hard sealing valve seat, which solves the problem of high temperature resistance.
If the external environment of the butterfly valve also needs to be anti-corrosion or anti-rust, the valve body needs to be made of stainless steel.
We can look at the picture below, the left is the lug butterfly valve, and the right is the wafer butterfly valve.
It is not possible to directly compare the advantages and disadvantages of the two.
When the butterfly valve is installed vertically upward or horizontally, the medium will erode the packing part.
