Product Details

NSV Fully Welded Ball Valves can be spherical and cylindrical type.Usually the spherical type have only one welding seam on the body,the cylindrical type have two welding seam on the body.The spherical body with single weld seam can integrate into two pieces bodies, and welding with circumferential weld.

The body of double weld seam fully-welded ball valve is composed three pieces,and have two circular and paraller weld seam,non-cross weld seam. The butted weld end is design with low stress and narrow gap type SAW process to reduce the amount of deposited metal. The carbonn equivalent is strictly controlled. At welding, the preheating and inter layer temperature are strictly controlled in order to meet
toughness and stress requirements of post weld body design standard
