PTFE Sleeved Plug Valve

Camtech 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. Few silent features are indicated as below,
Bi-directional in-line bubble-tight seal independent of line pressure
Multiple external bubble-tight seals independent of line pressure.
Direct mechanical three-point adjustment independent of line pressure
Independent travel stops
Full encapsulation and retention of all leading edges of PTFE sleeve and top seal components.
Full lip at port openings protects PTFE sleeve.
Contoured waterway ensures minimum flow turbulence characteristic.
No body cavities to entrap flow media.
Positive flow direction indication
