Frequently Ask Questions
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.
The wafer design provides a compact and lightweight installation between compatible pipeline flanges and requires less space than many flanged valve arrangements.
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.
Metal seating provides excellent resistance to high temperature, wear, thermal cycling and severe process conditions compared with conventional elastomeric seats.
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.
