2-1/2 Butterfly Valve BUNA

The Legend Valve 116-462 T-337AB-G is a ductile iron wafer butterfly valve designed for flow control in plumbing and industrial piping systems. It features an aluminum bronze disc and gear operator for reliable manual actuation. This new valve suits installers needing a quarter-turn shut-off solution compatible with BUNA seat requirements.

Gear Operated Ductile Iron Body

The gear operator provides mechanical advantage for opening and closing the valve under line pressure, reducing the torque required at the handwheel. This specification determines suitability for installations where lever operation would be impractical due to valve size or system pressure conditions. The ductile iron body offers structural strength for wafer-style mounting between flanges.

Aluminum Bronze Disc BUNA Seat

The aluminum bronze disc resists corrosion in water and compatible fluid services, while the BUNA seat provides sealing for general-purpose applications. The wafer body fits between standard flanges without additional gasket surfaces, freeing up pipeline space compared to lug or flanged designs. Installers must verify flange standard compatibility and fluid compatibility with BUNA elastomer before assembly. California Proposition 65 warnings apply for chemical exposure.

Questions about this item

What does the 2-1/2 size mean once the valve is in a real pipe run?

The 2-1/2 nominal size matches a 2-1/2 inch pipe schedule, so the wafer body sits between matching flanges and the disc clears the bore when fully open.

How does the gear operator change the way the valve is actuated?

The gear operator converts handwheel turns into a quarter-turn of the disc, giving mechanical advantage for higher line pressures without needing a long lever.

What flange pattern and bolt lengths does the wafer body require to mount?

The wafer design bolts between standard companion flanges; bolt length must cover both flange thicknesses plus the valve body and two nuts.
