Flange Butterfly Valves Collection

Flange butterfly valves come with a raised surface on the valve fitting that is mated to a facing groove, and this makes the connection between valves stronger and suitable for heavy-duty piping applications. With high-quality materials and optimized design, our valves work well in commercial and industrial applications with extreme temperatures.

DomBor Valve’s dedicated personnel operate within an advanced, safe factory that reaches quotas on time through our lean manufacturing. Our complete laboratory with high performance analyzers and non-destructive testing tools carries out thorough inspections to ensure every valve performs precisely within your specifications.
