Frequently Ask Questions

What Is a Sleeved Plug Valve?

A Sleeved Plug Valve is a quarter-turn plug valve in which the metal plug is surrounded by a polymer sleeve, commonly PTFE. The sleeve acts as the sealing surface between the plug and valve body.

Why Is a PTFE Sleeve Used?

PTFE provides a combination of chemical resistance, low friction and sealing performance, making it suitable for many corrosive and demanding process applications.

What Is a Cavity-Free Sleeved Plug Valve?

A cavity-free design minimizes spaces around the plug where process material could accumulate. This can help reduce material buildup, contamination and sticking in suitable applications.

How Does a Sleeved Plug Valve Work?

The plug rotates approximately 90° between the open and closed positions. The sleeve maintains contact around the plug and provides sealing while allowing the plug to rotate with low friction.

Does a Sleeved Plug Valve Require Lubrication?

No. A PTFE sleeved design is generally non-lubricated because the sleeve provides a low-friction, self-lubricating interface.

Who Is a Sleeved Plug Valve Manufacturer in India?

Alis Valves is a Sleeved Plug Valve manufacturer and supplier in India, offering sleeved plug valve solutions for chemical, petrochemical, oil & gas, refinery, mining and industrial process applications, with material and actuation options selected according to the service requirements.
