Sleeved Plug Valves
Sleeved Plug Valves
| Size | ½" to 16" |
| ASME Class | Class 150 to 300 |
| Design Standard | API 599, ASME B 16.34 |
L&T Valves offers a versatile range of PTFE Sleeved Plug Valves. The valves offer tight shutoff without sealants or lubricants and are available in sizes up to 400 mm, in ASME classes 150 and 300.
The interference fit of the taper plug with PTFE sleeve creates a bubble-tight seal. The sleeve totally surrounds the plug, and sealing occurs around the circumference of the plug. The integrity of the seal is totally independent of line pressure.
The rugged construction, reliable bubble-tight sealing and on-line maintenance feature make the valve an ideal choice for chemicals and highly aggressive process media.
