6-Inch Butterfly Valve

The Legend Valve 116-636 is a 6-inch T-367SS butterfly valve with a Buna seat. It uses a ductile iron body and a stainless steel disc for corrosion resistance. A 10-position lever handle provides manual flow control. This valve suits industrial and commercial piping systems.

Installers needing Buna compatibility

The Buna seat works with water, air and many non-aggressive fluids. Systems requiring EPDM, Viton or PTFE seats should choose a different valve. Automated processes needing pneumatic or electric actuation will not match the manual lever design. High-pressure steam or harsh chemical lines fall outside the intended service range.

10-position lever operation

The lever locks in ten discrete positions for throttling or isolation. Operators can balance flow without fine-thread adjustment. Frequent cycling or remote control needs exceed the manual handle design. Very large diameter mains or high-cycle automation require a different actuator style.

Questions about this item

What flange standard matches the 116-636 lug pattern for installation?

The 116-636 is a lug-type butterfly valve designed to bolt between mating flanges; verify the flange bolt circle and pressure class on site before fitting.

Will the 10-position lever handle clear adjacent pipework on a retrofit?

The handle locks in 10 discrete notches, so you can rotate it to the orientation that avoids nearby pipes or supports.

How do I confirm the Buna seat is sealing correctly after assembly?

Pressurise the line and inspect the disc-to-seat interface; zero visible leakage at the rated pressure confirms the Buna seal is seated properly.
