Five inch ductile iron wafer butterfly valve with aluminum bronze disc and gear operator

Legend Valve

Legend Valve 116-465 5" T-337AB-G Butterfly Buna Valve

SKU CH-HXVF-NT5MB

A 5-inch ductile iron wafer butterfly valve with an aluminum bronze disc and gear-operated BUNA seat

  • 5" ductile iron wafer butterfly valve for large-diameter flow control
  • Aluminium bronze disc resists corrosion in demanding fluid applications
  • Gear operated mechanism provides precise manual actuation
  • BUNA seat material compatible with water and oil-based media
  • California Proposition 65 listed for cancer and reproductive-harm chemicals

5" Ductile Iron Butterfly Valve

This 5" wafer-style butterfly valve uses a ductile iron body with an aluminum bronze disc and a Buna seat. Gear operation provides controlled flow regulation for plumbing and industrial piping systems. The valve is supplied new from Legend Valve under part reference 116-465.

Suits water and compatible fluid lines

Installers needing a gear-operated wafer valve with a Buna seal for general service will find this model appropriate. It is not intended for applications requiring a different seat material, a lever handle, or a lug-style body. Buyers who need higher pressure ratings or specific chemical compatibility beyond Buna should look elsewhere.

Gear operator eases installation effort

The valve mounts between flanges as a wafer unit, so alignment of the surrounding pipework is the main practical step. Common issues include flange face damage that prevents a seal, incorrect bolt length for the wafer thickness, and debris left in the line that can score the Buna seat during first operation.

Questions about this item

What pipe size and flange standard does the 5" T-337AB-G butterfly valve require for installation?

The valve fits a 5 inch wafer connection between matching flanges; you need compatible flange faces, bolts, nuts and gaskets rated for the system pressure.

Can the aluminum bronze disc and Buna seat handle the same fluids as my existing ductile iron body valves?

The aluminum bronze disc and Buna seat resist many water and oil based media; verify chemical compatibility with your specific fluid before pairing with older ductile iron bodies.

How do I confirm the gear operator on the 116-465 valve moves the disc fully open and closed after installation?

Turn the handwheel through its full travel and watch the position indicator; the disc should align parallel to flow when open and perpendicular when closed.
