Jacket ball valve
BQ41H/PPL-16~100C,P,R
The product description
BQ41F PN16, PN20, PN25 insulation jacket ball valve has good thermal insulation and cold characteristics, and the valve diameter is consistent with the pipe diameter, but also can effectively reduce the heat loss in the pipeline medium. It is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport high viscosity media that can be solidified at normal temperature.
