Legend Valve

Legend Valve 116-406 6" T-335AB Butterfly Valve EPDM

SKU CH-ZTBW-W34DG

A 6-inch ductile-iron wafer butterfly valve with an aluminum-bronze disc, EPDM seat and a 10-position lever handle

  • 6-inch wafer design fits standard flanges
  • Ductile iron body resists pressure and corrosion
  • Aluminum bronze disc handles abrasive media
  • 10-position lever allows precise flow control
  • EPDM seat suits water and glycol systems

6" Ductile Iron Wafer Butterfly Valve

This 6-inch wafer-style butterfly valve uses a ductile iron body with an aluminum bronze disc and EPDM seat. It suits commercial and industrial plumbing systems that need on-off or throttling control in compatible water and chemical lines. The lever handle provides ten locking positions for repeatable flow settings. Installers who need flanged connections or a different seat material should look elsewhere.

Capacity and pressure headroom

The ductile iron construction handles typical HVAC and process-piping pressures while the EPDM seat resists hot water and many dilute acids. The ten-position lever gives fine adjustment through mid-range flow but is not designed for precise metering or high-cycle automation. Systems requiring actuated operation or higher temperature ratings exceed the design intent of this valve.

Replaces older wafer butterfly valves

This unit replaces legacy wafer butterfly valves of the same 6-inch size and pressure class when the disc and seat materials match the service conditions. The jump is worth it when the existing valve shows seat wear, disc corrosion or handle slippage. It does not replace lug-style or flanged valves without piping modifications.

Highlights

  • 6-inch wafer design fits standard flanges
  • Ductile iron body resists pressure and corrosion
  • Aluminum bronze disc handles abrasive media
  • 10-position lever allows precise flow control
  • EPDM seat suits water and glycol systems

Questions about this item

Will the 116-406 valve align with my existing 6-inch flanges?

The 116-406 is a 6-inch wafer butterfly valve designed to fit between standard 6-inch pipe flanges.

How can I verify the 10-position lever handle is operating correctly after installation?

The lever handle clicks into 10 distinct detent positions; each click corresponds to a set disc angle from fully closed to fully open.

Does the 116-406 package include flange gaskets and bolts, or must I source them separately?

The valve ships as the wafer body with the aluminum bronze disc and EPDM seat installed; flange gaskets and bolts are not included and must be purchased separately.
