4-Inch Ductile Iron Butterfly Valve

The Legend Valve 116-464 is a 4-inch wafer-style butterfly valve built from ductile iron with an aluminum bronze disc. It uses a gear operator for manual flow control in commercial and industrial piping systems. The BUNA seat provides compatibility with water, oil and general-purpose fluids. It is not suited for buyers who need automated actuation or sanitary-grade materials.

California Proposition 65 Compliance Notice

This product carries a California Proposition 65 warning because it contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The notice applies to the valve materials as supplied and does not describe thermal, noise or power characteristics. Installers should review the warning before handling or installing the unit in regulated environments.

Gear Operator and BUNA Seat Details

The gear operator allows precise manual throttling without the need for external power or pneumatic lines. The BUNA seat seals against the aluminum bronze disc to handle standard temperature and pressure ranges for water and hydrocarbon service. No additional accessories, software or actuation kits are included with the valve.

Questions about this item

How do I install the 4" T-337AB-G wafer butterfly valve and what step is often missed?

Fit the valve between two flanges with a gasket on each face, then tighten the bolts in a star pattern; the step often missed is centring the disc so it does not bind against the flange bores.

What maintenance will the Buna seat and aluminium bronze disc need over time?

Inspect the Buna seat for swelling or cracking from chemical exposure and cycle the gear operator quarterly to prevent seizing; replace the seat if leakage appears at the disc edge.

What limit appears first when the valve is cycled frequently under pressure?

The Buna seat temperature ceiling of 65 °C is reached first; sustained operation above that accelerates hardening and shortens seal life.
