The 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.

The ball valve are designed in accordance with ISO17292?BS 5351?API6D?API607 Simple structure with good tightness and small torque; Have reduce bore type and full bore type with the minimum flow resistance (zero actually); Low emission packing; Fire safe, anti-static and anti-blowout stem design; Optional ISO 5211 top flange   Product Range Body material: ASTM?A105?LF2?F11?F22?F304?L??F316?L??F51?F6a?20Alloy ect. Nominal diameter:1/2"?6"?DN15~DN150??
