Features 
 The product has good insulating properties of cold, and the valve diameter and the diameter of the same media, small flow resistance, optimal security and easy freezing, high-viscosity media. While the media in the pipeline to reduce heat loss. As a result of the overall structure, and thus insulation ball valve smaller than normal, lighter, and no leakage, good sealing performance, carbon steel welded jacket with more pressure than the solid casting. This series of valves can be equipped with pneumatic, electric and other drive.
