PTFE Sleeved Plug Valve
Sleeved Plug valves are robust in construction and easy In-Line maintainability. These valves are non-lubricated quarter-turn valves that achieve sealing through the use of a compressible sleeve as a sealing member. In many applications they operate virtually maintenance free for decades. Sleeved plug valves are used for on/off and throttling service in demanding process applications with media temperatures ranging from -20°F to 600°F. These valves are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, electric power industry etc.
These valves are Bi-directional flow, simple actuation, lightweight, compact design, and multiport configurations, all facilitate for improved system design. The inert PTFE sleeve completely surrounds the plug. The sleeve provides a large, circumferential sealing surface from port to port. Open, closed, or rotating, the seal is assured. As the plug rotates, the 360° port lips provide a self-cleaning action to remove scaling and adhering media.
