There are two types of plug valves: lubricated and non-lubricated. Lubricated versions use a sealant like grease or oil to reduce friction between metal surfaces, while non-lubricated valves rely on special coatings to prevent sticking.

Plug valves come in several configurations, including straight-through (or “full bore”) models that provide unobstructed flow paths for minimal pressure drop. Another common type is called a “reduced port” valve, which has smaller openings than full-bore designs but can still offer precise control over fluid movement.

1.Flow Regulation – Tight shut-off, quick opening and low-pressure drop.

2.Fire-safety and Durability – Reduced likelihood of corrosion or erosion as the actual plug and body seating surface do not get exposed to the line fluid.

3.Versatility – You can use plug valves with large flow rates as well.
