Frequently Ask Questions

What Is a Lug Type Metal Seated Butterfly Valve?

It is a lug-style butterfly valve with metal-to-metal sealing surfaces, designed for high-temperature, high-pressure and demanding industrial applications.

Who Is a Lug Type Metal Seated Butterfly Valve Manufacturer in India?

Alis Valves manufactures and supplies Lug Type Metal Seated Butterfly Valves for oil & gas, refineries, petrochemical, power generation, chemical, steam, hot-oil, cement, steel and other severe-service industrial applications.

What Is the Advantage of Lug-Type Construction?

The lug body contains individual threaded mounting points, allowing the valve to be securely bolted to the pipeline flanges.

What Is the Main Advantage of a Metal Seat?

A metal seat provides excellent resistance to high temperature, wear, thermal cycling and severe process conditions, where rubber or other elastomeric seats may have limitations.
