VB100 Low-Temperature Butterfly Valve (end-use temperature -196℃~+100℃/Corrosion resistance and friction )

VB100 low temperature butterfly valve is a three eccentric sealing butterfly valve, the sealing surface of cone plane type, there is an angle eccentric in the horizontal center, the center of the valve in two distances in its axial and radial eccentric, sealing side is independent removable structure, low temperature condition deformation approximate consistent, ensure good sealing,: and can realize the rapid replacement and maintenance of interior.

1.VB100 low-temperature butterfly valve adopts three eccentric structure, there is no dead zone during the valve opening and closing process, and the opening torque is small.
2. The sealing ring adopts integral metal overwelded hard alloy to improve the corrosion resistance and friction wear resistance of all metal butterfly valve,
3. The independent valve seat seal ring structure is adopted to ensure that the low temperature butterfly valve has good sealing performance under ultra-low temperature working conditions. 4. The elongated valve cover is adopted to keep the valve stem packing away from the low temperature medium to ensure the packing reliability of the material and its service life.
5. The packing system adopts the disc spring dynamic loading compensation structure to avoid the medium leakage at the packing site, and can meet the requirements of TA-Luft standard.
