SKU CH-3WEV-ZNFR4

A 3-inch ductile-iron wafer butterfly valve with an aluminum-bronze disc, gear operator and Buna seat

  • 3" ductile iron wafer butterfly valve for pipeline control
  • Aluminum bronze disc resists corrosion in water systems
  • Gear operated mechanism enables precise flow regulation
  • Buna-N seat provides reliable sealing performance
  • California Proposition 65 warning for chemical exposure awareness

3-Inch Ductile Iron Butterfly Valve

This 3-inch wafer-style butterfly valve uses a ductile iron body with an aluminum bronze disc and BUNA seat material. Gear operation provides mechanical advantage for opening and closing the valve in plumbing installations. The Legend Valve 116-463 model is supplied new and ships directly from the manufacturer.

Installation Compatibility Checks

Verify that the pipeline flange spacing matches a wafer-style valve body and that the bolt pattern aligns with the 3-inch nominal size. Confirm the process media is compatible with BUNA elastomer and aluminum bronze wetted parts before installation. Ensure adequate clearance exists for the gear operator handwheel and that system pressure falls within the valve's rated limits.

Suitable Applications and Limitations

This valve suits water, HVAC and compatible fluid systems requiring a gear-operated shut-off or throttling device with BUNA sealing. Buyers needing a different seat material for chemical compatibility or a lever-operated valve for quicker manual action should look elsewhere. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm.

Questions about this item

Does the 116-463 butterfly valve include any gaskets, bolts or installation hardware in the box?

The valve ships as the bare T-337AB-G body with BUNA seat and gear operator; companion flanges, gaskets and mounting bolts must be sourced separately.

How do I choose between the available versions of the 116-463 valve for my application?

The 116-463 is offered only as a 3-inch ductile-iron wafer with aluminum-bronze disc, BUNA seat and gear operator — no alternative trim or actuation options are listed.

What does the 65 warning on the 116-463 valve mean for daily use in a plumbing system?

Proposition 65 indicates the valve contains a chemical known to California to cause cancer or reproductive harm; normal handling and installed service do not change that classification.
