BQ41F保温夹套球阀

Features

The product bears favorable heat-preservation and cold-insulation specialties.In addition, the all-diameter of the valve is identical to pipe diameter to effectively reduce the heat loss from those medium in the pipeline. It is mainly applied to transport the full- bodied mediums which solidify under normal temperature in such fields as petroleum industry, chemical industry, metallurgical industry, pharmaceutical industry,food industry, etc.
For the monolithic construction is applied in design the product, the jacket valve with favorable sealing performance features smaller configuration and weight than traditional ball valves without leakage. More overpressure-resistant and firmer capacities are also
enjoyed by the jacket made through carbon steel welding than that through casting.
