Frequently Ask Questions

What Is a Lubricated Plug Valve?

A Lubricated Plug Valve is a quarter-turn valve that uses a special lubricant between the plug and body to reduce friction and improve sealing during operation. It is commonly used for reliable isolation of gas, oil and other industrial fluids.

Why Is Lubricant Used in a Plug Valve?

The lubricant helps reduce friction between the plug and body, supports smoother operation and helps maintain sealing performance.

What Happens if the Lubricant Is Not Maintained?

Insufficient or unsuitable lubricant can increase operating friction and may negatively affect sealing and valve performance. The manufacturer's recommended sealant and maintenance procedure should be followed.

How Does a Lubricated Plug Valve Work?

The valve contains a tapered or cylindrical plug with a flow passage. When the plug is rotated, the passage aligns with the pipeline to allow flow. Rotating it approximately 90° moves the plug into the closed position and isolates the flow.

What Is the Difference Between Lubricated and Non-Lubricated Plug Valve?

A lubricated plug valve uses sealant/lubricant between the plug and body to reduce friction and assist sealing. A non-lubricated plug valve uses a different design, often incorporating sleeves or special lining systems, to achieve low-friction operation without routine plug lubrication.

Who Is a Lubricated Plug Valve Manufacturer in India?

Alis Valves is a Lubricated Plug Valve manufacturer and supplier in India, offering lubricated plug valves for oil & gas, refinery, petrochemical, chemical and high-pressure industrial applications, with sizes from DN15 to DN300 and pressure classes from Class 150 to 900.
