| 1、Features |
| The product bears favorable heat-prserviton and cold-insulation specialties. Inaddition, the all-diameter of the valve is identical to pipe diaeter to effectively reducethe heat loss from those medium in the pipelines. It is maimly applied to transport the full-bodyed mediums which solidify under normal temerature in such fields as perroleum industry, chemical industry, metallurgical industry, pharmaceutical industry, food industry, etc. For the monolithic constrution is applied in deaign the product, the jacket valve with favorable sealing performance features smaller configuration and weight than traditional ball valves without leakage. More overpressure-resistant and firme capacities are also enjoyed by the jacket made through carbon steel welding than through casting. |
