AUDCO 2 Piece Design Ball Valve
Audco 2-Piece Design Ball Valves (manufactured under L&T Valves / Audco) are split-body, end-entry isolation valves designed for tight shut-off, low operating torque, and high flow efficiency. Featuring a sturdy 2-piece body held together by heavy-duty bolting, these valves eliminate potential leak paths compared to 3-piece variants while offering full-bore straight-through flow across process pipelines.
