API6d Trunnion Forged Steel Ball Valve
MAIN FEATURES:The YFV FIX 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.
fix trunnion 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.
