Butterfly Valves
 

Weir SPM butterfly valve's specially designed disc allows for a noticeably smoother media flow, reducing or eliminating turbulence commonly found in other valves. Another superior design feature is the split stem, which allows the disc to automatically center in the media flow path, thus assuring an even seal around the disc. A one-piece phenolic back-up ring allows internal pressure to anchor the seat within the valve body and prevents seat walking. Various seat and disk materials
are available.

Available in Sizes ranging from 3 Inches to 12 Inches.
