SKU CH-687N-5C7EW

Eight-inch ductile iron lug-type butterfly valve with stainless steel disc, Buna seat and ten-position lever handle

  • 8" ductile iron lug butterfly valve for large pipeline control
  • Stainless steel disc resists corrosion in demanding fluid applications
  • Buna seat provides reliable sealing across compatible media types
  • 10-position lever handle allows precise flow adjustment
  • California Proposition 65 warning for chemical exposure awareness

8-Inch T-367SS Butterfly Valve

The Legend Valve 116-637 is an 8-inch T-367SS butterfly valve with a Buna seat designed for flow control in plumbing systems. It features a ductile iron body and a stainless steel disc for corrosion resistance. A 10-position lever handle allows precise manual adjustment of the valve opening.

Suits installers needing lug-type mounting

This valve suits installers who require a lug-type butterfly valve for dead-end service or easy piping removal. It is not for buyers who need a wafer-style body that fits between flanges without bolts. It also does not suit applications requiring an EPDM or Viton seat instead of Buna material.

Lever handle enables straightforward operation

The 10-position lever handle enables straightforward manual operation and locking at set angles. Lug bolting requires alignment with flange holes to prevent binding. Buna seats can swell or degrade if exposed to oils, hydrocarbons or temperatures outside the material's compatible range.

Questions about this item

What pipe size and flange standard does the 116-637 valve need to bolt onto?

The 116-637 is an 8 inch lug-type butterfly valve; it requires matching 8 inch flanges with bolt holes that align to the valve’s lug pattern.

Will the Buna seat on this T-367SS valve handle the same fluids as the older EPDM seat I have in service?

Buna resists oils and hydrocarbons better than EPDM, but it is not suitable for hot water or steam services where EPDM performs well.

How can I verify the 10 position lever handle on the 116-637 is locking in each notch after installation?

Operate the handle through all 10 notches; each click should hold the disc firmly without spring-back, confirming the locking mechanism engages correctly.
