Key specifications

Choosing the right option

The flange is drilled to the TTMA pattern, so confirm your mating flange before ordering. This is a simple open/closed valve; where you need to hold the disc part-open, use the metering handle version: Betts Flanged Butterfly Valve - Metering.

Dixon also offers replacement handle assemblies and dual-actuated versions of these valves under separate part numbers.
