  • 2-1/2" wafer body fits tight pipe spacing
  • Aluminum bronze disc resists corrosion in water service
  • Buna seat handles common plumbing fluids
  • 10-position lever gives repeatable flow control
  • Ductile iron construction withstands normal system pressure

2-1/2" Ductile Iron Butterfly Valve

This 2-1/2" wafer butterfly valve uses a ductile iron body with an aluminum bronze disc and a BUNA seat. It is built for commercial and industrial piping systems that need reliable shut-off or throttling. The 10-position lever handle gives operators clear detents for flow control.

Aluminum Bronze Disc Upgrade

The aluminum bronze disc replaces standard iron or steel discs in applications where corrosion resistance matters. The jump is worth it when the media attacks lesser alloys or when longer service intervals are required. The BUNA seat handles water, air and many inert gases within its temperature range.

10-Position Lever Headroom

Ten lever positions provide fine adjustment for balancing and isolation duties. The valve runs out of headroom when line pressure exceeds the wafer body rating or when the media degrades BUNA above its chemical limit. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

What pipe size and flange type does the 2-1/2" T-337AB wafer butterfly valve fit?

The valve is a wafer-style body designed to sit between standard flanges for a 2-1/2 inch pipeline.

How do I install the 10-position lever handle so the aluminum bronze disc seals correctly?

Bolt the wafer body between flanges with the disc partially open, then attach the lever handle onto the stem flats in the closed position.

When should I replace the Buna seat in this 116-422 valve?

Replace the Buna seat if it shows cracking, swelling, or if the valve leaks when the lever is in any of the 10 latched positions.
