Plug  Valves

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.

Plug valves usually do not have bonnets but often have the end of the plug with the handle exposed or mostly exposed to the outside. In such cases, there is usually not much of a stem. The stem and handle often come in one piece, often a simple, approximately L-shaped handle attached to the end of the plug. The other end of the plug is often exposed to the outside of the valve too, but with a mechanism that retains the plug in the body.

  1. Sleeve Type Plug Valve

  2. Lubricated Plug Valve

  3. Lift Type Plug Valve

 

  1. Sleeve Type Plug Valve

Sleeved plug valves are non-lubricated quarter-turn valves that achieve sealing through the use of a compressible sleeve as a sealing member. Sleeve Type Plug Valve characteristic double-direction flow makes installation and use more convenient. Sleeved type soft sealing plug valves can be used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry, mining, etc.
