Summary:
200J type of Heat preservation ball valve is designed in fixture form, with reasonable structure, light weight, excellent sealing performance and good heat preservation and cold insulation characteristics. The diameter of the valve is in consistent with that of pipeline, with little fluid resistance, which can reduce the heat loss of medium in pipeline effectively and prevent the solidification of sticky fluid in pipeline. It is widely used in such industries as oil, chemical engineering, pharmacy and metallurgy.
