  • Buna-N seat delivers reliable sealing across compatible media
  • California Proposition 65 warning: contains chemicals known to cause cancer and reproductive harm

3" Ductile Iron Butterfly Valve

The Legend Valve 116-663 is a 3-inch lug-type butterfly valve built for flow control in plumbing systems. It features a ductile iron body with an aluminum bronze disc and BUNA seat material. Gear operation provides mechanical advantage for opening and closing. This new valve suits industrial and commercial piping installations.

Verify Pipe Size and Seat Compatibility

Confirm the existing pipeline matches the 3-inch nominal diameter before ordering. Check that BUNA elastomer is compatible with the intended fluid media and operating temperature range. Ensure the lug pattern aligns with the mating flanges and bolt hardware on site. Review the Proposition 65 notice regarding listed chemicals.

Gear Operator and Lug Mounting

The gear operator reduces hand effort required to actuate the valve under pressure. Lug-style mounting allows the valve to be installed or removed without disturbing the adjacent pipe run. Ductile iron construction resists mechanical shock and vibration in service. Aluminum bronze disc material offers corrosion resistance for extended service life.

Questions about this item

Does the 116-663 valve come with flange gaskets and mounting bolts, or do I need to buy them separately?

The 116-663 butterfly valve is supplied as the valve body only; flange gaskets and mounting hardware must be purchased separately for installation.

How do I decide between the T-367AB-G gear-operated model and a lever-operated version for a 3-inch line?

Choose the T-367AB-G gear operator when the 3-inch valve requires lower operating torque or will be installed where a lever cannot swing freely.

What does the Buna seat designation mean for fluid compatibility on the 367 series?

The Buna-N seat on the 367 series handles water, air and many petroleum-based fluids, but is not suitable for strong acids, ketones or chlorinated hydrocarbons.
