Frequently Ask Questions
It is a double-offset butterfly valve with a metal-to-metal sealing arrangement, designed for high-temperature, high-pressure and demanding industrial applications.
The double-offset geometry allows the disc to move away from the seat early during opening, reducing friction, rubbing and seat wear.
A metal seat provides excellent resistance to high temperature, wear and demanding process conditions, where conventional elastomeric seats may have limitations.
Alis Valves manufactures and supplies Metal Seated Double Offset Butterfly Valves for oil & gas, petrochemical, power generation, chemical processing, steam, refinery and other severe-service industrial applications.
