Stainless steel butterfly valve with lever handle

Legend Valve

Legend Valve 116-433 3" T-337 SS Butterfly Valve BUNA

SKU CH-V6CW-WH8XS

Three-inch stainless-steel butterfly valve with BUNA seat and ten-position lever handle

  • Stainless steel disc resists corrosion for longer service life
  • BUNA seat material suits water and general fluid applications
  • 10 position lever handle gives precise flow control
  • Ductile iron wafer body provides strength in compact piping
  • California Proposition 65 notice included for regulatory awareness

3-inch T-337 Stainless-Steel Butterfly Valve

This 3-inch Legend Valve butterfly valve uses a stainless-steel disc and BUNA seat to control flow in plumbing systems. The wafer body fits between standard flanges and the 10-position lever handle provides positive shut-off. It is supplied new for commercial and industrial piping installations.

Sustained-pressure behaviour

The stainless-steel disc resists corrosion during continuous service while the BUNA seat maintains sealing integrity under steady pressure. The lever handle stays fixed in any of its 10 detent positions without creep. California Proposition 65 warnings note chemical content that installers should review before long-term deployment.

Installation notes and common issues

The wafer design centres between mating flanges so alignment is critical to avoid seat damage. Installers sometimes over-tighten flange bolts, which distorts the body and prevents the disc from seating fully. The 10-position handle can bind if debris enters the stem area during assembly.

Questions about this item

How much heat does the 116-433 valve generate during continuous operation?

The 116-433 is a passive mechanical valve with no electrical components, so it produces no heat of its own.

What pipe flanges or gaskets are required to install the 116-433 valve?

The 116-433 is a wafer-style butterfly valve designed to fit between standard flanges; you must supply matching flanges, bolts and gaskets.

Will the 116-433 valve mate with my existing 337-series ductile iron piping?

The 116-433 uses a wafer pattern that aligns with common flange standards, so it can connect to 337-series piping when the flange dimensions match.
