Frequently Ask Questions

What Is a Flanged Triple Offset Butterfly Valve?

It is a triple-eccentric butterfly valve with metal-to-metal seating and integral flanges on both sides, designed for demanding high-temperature and high-pressure applications.

Can Tungsten Carbide Coating Be Used?

Yes. Tungsten-carbide and other hard-facing options can be considered for abrasive or high-wear applications.

What Is the Main Advantage of Triple Offset Design?

The main advantage is non-rubbing sealing. Unlike conventional butterfly valves, the disc does not continuously rub against the seat, reducing friction and seat wear.

What Are the Three Offsets?

The design incorporates two eccentric shaft/disc offsets and a third offset in the conical sealing geometry. This creates a cam-like movement that removes the disc from the seat during opening.

Who Is a Flanged Triple Offset Butterfly Valve Manufacturer in India?

Alis Valves manufactures and supplies Flanged Triple Offset Butterfly Valves for oil & gas, refineries, petrochemical, power generation, chemical, steam, hot oil, cement, steel, flue gas and other severe-service industrial applications.
