Legend Valve

Legend Valve 116-635 5" T-367SS Butterfly-Buna Valve

SKU CH-YY1D-JRG74

A 5-inch ductile iron lug-type butterfly valve with a stainless steel disc, Buna liner, and 10-position lever handle

  • 5-inch ductile iron body handles high-pressure flow
  • 10-position lever handle gives precise flow control
  • Stainless steel disc resists corrosion for longer life
  • Buna-N seat provides reliable sealing performance
  • Lug-type design allows easy installation and maintenance

5-inch Butterfly-Buna Valve

The Legend Valve 116-635 is a 5-inch T-367SS butterfly valve with a Buna seat for fluid control. It serves plumbing professionals and facility maintenance teams who need a quarter-turn shut-off device. The ductile iron body and stainless steel disc suit water and compatible media. Buyers who require a different seat material or flange connection cannot use this model.

Thermals Noise and Power Draw

This mechanical valve has no electrical components, so it generates no heat, noise or power draw during operation. Flow resistance depends on the disc position and media properties. The 10-position lever handle allows manual throttling without actuators. Installers who need automated actuation or telemetry feedback must add separate equipment.

Included Lever Handle Benefit

The supplied 10-position lever handle locks the disc at set angles for repeatable flow settings. It removes the need to source a separate operator and speeds up field installation. The handle mounts directly to the valve stem with standard hardware. Systems that require pneumatic or electric operators will not use the included lever.

Questions about this item

How is the 5-inch T-367SS butterfly valve installed and what step is often missed?

Mount the lug-type body between flanges using bolts through every lug hole; the step often missed is tightening the bolts in a cross-pattern sequence so the Buna seat seals evenly.

What maintenance will the Buna seat and stainless steel disc need later?

Inspect the Buna seat for swelling or cracks each year and replace it if the material has degraded; the stainless steel disc only needs cleaning if debris builds up on the sealing surface.

What limit appears first when the valve cycles repeatedly under pressure?

The Buna seat reaches its temperature and chemical resistance limit before the ductile iron body or stainless steel disc, so seat wear dictates the replacement interval.
