Audco Regular Pattern Plug Valve
Audco Regular Pattern Plug Valve: Technical Overview & Specifications
The Audco Regular Pattern Plug Valve is a heavy-duty, quarter-turn industrial valve designed for isolating and controlling fluids, gases, steam, slurries, and aggressive chemicals. Featuring a plug port area substantially equal to the pipe bore area, it provides efficient full-flow performance across standard process applications.
