Alis Valves is a trusted Lubricated Plug Valve Manufacturer Supplier in India designed for efficient flow control in high-pressure and high-temperature applications. These valves utilize a special lubricant injected between the plug and body to reduce friction, ensure tight sealing, and enhance performance. The robust design and reliable sealing make them suitable for handling gases, oils, and other demanding media in critical industrial processes.      

Product Specifications and Overview

ALIS Valves offers Lubricated Plug Valves for industrial applications requiring reliable flow isolation, tight shut-off and smooth valve operation. These valves feature a tapered or cylindrical plug with a flow passage that rotates to open or close the valve. A specially designed lubricant is injected between the plug and body sealing surfaces to reduce friction, support smooth operation and help improve sealing performance. The lubricant also helps minimize wear between contact surfaces, making these valves suitable for compatible applications involving demanding pressure and operating conditions.

Lubricated Plug Valves are suitable for applications in oil and gas facilities, refineries, petrochemical plants, chemical processing industries and industrial pipeline systems. Depending on the valve design and material specifications, they can be used with compatible liquids and gases across a range of operating conditions. Important selection factors include operating pressure, temperature, process media, valve size, plug and body materials, lubricant compatibility, sealing requirements and end connection type. Selecting the appropriate Lubricated Plug Valve helps support dependable shut-off, reduced operating friction and reliable performance under the intended working conditions.

Frequently Ask Questions

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