1. Product features of BQ41F integrated thermal insulation ball valve
The product has good heat preservation and cold preservation characteristics, and the diameter and pipe diameter of the valve can effectively reduce the heat loss of the medium in the pipeline. It is mainly used in various systems such as petroleum, chemical industry, metallurgy, pharmacy, food, etc., to transport high-viscosity media that solidify at room temperature.
Due to the integrated structure, the thermal insulation ball valve is smaller and lighter than the general ball valve, has no leakage, and has good sealing performance. The jacket is welded by carbon steel pipe and is more pressure-resistant and firmer than the cast one.
