FLANGE-CONNECTION HEATING BALL VALVE
A. CONNECTION HEATING BALL VALVE 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 reduce the heat loss effectively from those medium in the pipeline. It is applied mainly 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 the product's design, the jacket valve with favorable sealing performance features by 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.
