Cast Iron ANSI Ball Valves are industrial shut-off valves designed to American standards. Typically featuring a cast iron (ASTM A126 Class B) or ductile iron body, they utilize a floating stainless steel ball for reliable sealing. They follow ASME B16.10 for face-to-face dimensions and ASME B16.1 for flanging. Most common in Class 125 and 150, they are used for water, oil, and gas. They offer a cost-effective, full-bore solution with soft PTFE seats for bubble-tight shut-off.
