In the pipeline system and device of low temperature medium, the low temperature ball valve with valve cover should be selected.
Flanged telescopic butterfly valve, the structural length can be expanded and retracted within a certain range.
The wear of the valve seat and the valve disc is reduced, and the service life of the valve seat is improved.
There are two common connection methods: wafer and flange, and common materials are cast iron, ductile iron, cast steel, and stainless steel.
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.
