The Type of Grooved Butterfly Valve

by Adamant Valves

There’re two sealing types for butterfly valve—metal sealing and elastic sealing.

Valves that use metal sealing usually last longer than valves that use elastic sealing, but they are difficult to be completely sealed. Metal sealing can endure high working temperature while elastic sealing is limited to changes in temperature. If the butterfly valve is used to regulate flow, it is important to correctly select the size and type of the valve.
