Pneumatc Short Type Jacketed Floating Ball Valve (GBQ71F) characteristic.
It 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 pipelines. It is mainly applied to transport the high viscosity medium which solidity under normal temperature in such fields as
 petroleum industry, chemical industry, metallurgical industry, pharmaceutical industry, food 
industry.
For the monolithic construction is applied in design the product , the jacketed  valve with favorable sealing performance features smaller configuration and weight than traditional ball valves without leakage . More over pressure-resistant and firmly  capacities are also enjoyed by the jacket made through carbon steel welding.
