3.Application of High Performance Double Offset Butterfly Valve
High performance double offset butterfly valve is mainly used in the preheating system and dry dust removal system of the ironmaking blast furnace with large nominal diameter, low working pressure and opening and closing pressure difference, and high temperature (200~350 ℃). Air shut-off valve, combustion-supporting gas shut-off valve, gas inlet shut-off valve of heat exchanger system, flue gas inlet shut-off valve of heat exchanger system and gas shut-off valve of dry dust removal system, etc.
4.Features of High Performance Double Offset Butterfly Valve
1) The outer circumference of the disc and the sealing valve seat of the High performance double offset butterfly valve are processed into a hemispherical surface, and the inner spherical surface of the sealing valve seat is squeezed by the outer spherical surface of the disc to produce elastic deformation to achieve the purpose of closing tightly.
2) High performance double offset butterfly valve usually uses tetrafluoroethylene material as its sealing valve seat, but also can use Jinli sealing valve seat to improve its application in high temperature field.
3) High performance double offset butterfly valve The sealing surface of the butterfly plate and the valve seat is in line contact. If you are in a high-pressure environment, do not choose a metal sealing valve seat.
