Single Offset vs Double Offset vs Triple Offset Butterfly Valves – What’s the Difference?

In corrosive environments involving seawater, brine, acids, caustics, hydrocarbons, or chemical slurries, valve materials and seating mechanisms must deliver long-term durability. Offset butterfly valves are designed to reduce contact between the disc and seat, minimizing wear and extending operating life. Materials used for corrosive applications include: Understanding the offset configuration helps determine which material and
