Frequently Ask Questions

What Is a Wafer Type Metal Seated Butterfly Valve?

It is a wafer-style butterfly valve with metal-to-metal sealing surfaces, designed for isolation and flow control in high-temperature and demanding industrial services.

What Is the Advantage of Wafer Construction?

The wafer design provides a compact and lightweight installation between compatible pipeline flanges and requires less space than many flanged valve arrangements.

What Is the Difference Between Metal Seated and Rubber Seated Butterfly Valves?

A rubber-seated valve uses an elastomeric seat and is generally preferred for moderate-temperature services. A metal-seated valve is better suited to high-temperature, high-wear and severe-service applications.

What Is the Main Advantage of Metal Seating?

Metal seating provides excellent resistance to high temperature, wear, thermal cycling and severe process conditions compared with conventional elastomeric seats.

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

Alis Valves manufactures and supplies Wafer Type Metal Seated Butterfly Valves for oil & gas, refineries, petrochemical, power generation, chemical, steam, hot oil, cement, steel, flue gas and other demanding industrial applications.
