ANSI Sleeved Plug Valve 

Plug valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open. Plug valves are simple and often economical. Sleeved plug valves are non-lubricated quarter-turn valves that achieve sealing through the use of a compressible sleeve as a sealing member.  Sealing member can be hard seal and soft seal which normally applicated in petrochemical industry, pharmaceutical factory, chemical fertilizer etc with maintenance free for decades. Sleeved plug valves are used for on/off and throttling service in demanding process applications with media temperatures ranging from -29℃ to 180°F. Standard sizes from 1/2" to 24", ANSI classes 150,300 & 600. Body & plug materials range from  carbon steel , stainless steel, duplex steel. …
