MAIN FEATURES
Fully-welded ball valve adopts forged material, welded body, instead of bolts and nuts, to aviod any potential leakage from body. The forged body with regular structure and even thickness can avoid shrinkage cavities, pin holes, cracks, sand holes and other defects occurring to casting body valves.
Fully-welded ball valves can be spherical and cylindrical type. Usually the spherical type has only one welding seam on the body, the cylindrical type has two welding seam on the body.
Welded ball valve is widely used in various fields, its superior quality and high performance stability is ordinary cast steel ball valve can not reach, all-welded ball valve service life is far greater than cast steel ball valve
Design Features
The ball valve are designed in accordance with ISO14313,API 6D;
Simple structure with good tightness and small torque;
With a fully-welded valve body, full bore and the minimum flow resistance (zero actually);
Emergency sealant injection;
Cavity pressure self relief;
