Audco Globe Valve
Audco Globe Valves (manufactured under L&T Valves / Audco) are linear-motion valves engineered for precise flow regulation, throttling, and tight shut-off in critical process pipelines. Featuring a ball-type disc, outside screw and yoke (OS&Y), and bolted-bonnet design, these valves are built for reliability across high-pressure and high-temperature environments.
