4-Inch T-337 Stainless Steel Butterfly Valve

This Legend Valve 116-434 model uses a 4-inch wafer body with a stainless steel disc and Buna seat for fluid control. The 10-position lever handle lets operators set flow in discrete steps. It suits commercial and industrial plumbing systems that require a quarter-turn shut-off valve with a resilient seal.

Ductile Iron Wafer Body with 10-Position Lever

The wafer design fits between standard flanges without extra gaskets, reducing installation hardware. Ductile iron construction resists mechanical stress while the stainless disc resists corrosion from the media. The lever locks in any of the 10 notches, giving clear visual confirmation of the valve position during daily operation or maintenance checks.

Buna Seat and California Proposition 65 Notice

The Buna-N seat handles water, oil and air within its temperature and pressure limits, providing a tight seal without additional packing. California Proposition 65 warnings apply because the product contains chemicals identified by the state as causing cancer and reproductive harm; installers should follow local safety regulations and use appropriate personal protective equipment when handling or servicing the valve.
