  • Gear operator provides controlled open and close action
  • Buna seat seals reliably across wide temperature range
  • California Proposition 65 warning included for regulated substances

8-inch lug butterfly valve

The Legend Valve 116-667 is an 8-inch ductile iron lug-type butterfly valve designed for flow control in commercial and industrial piping systems. It features an aluminum bronze disc and a gear operator for manual actuation. The valve uses BUNA seating material for compatible media sealing. It is supplied new for direct installation.

Gear operator and disc material

The gear operator provides mechanical advantage for opening and closing the valve under line pressure without external power. The aluminum bronze disc offers corrosion resistance suitable for water, seawater, and various chemical services. The BUNA seat delivers a resilient seal for the intended temperature and pressure range. No additional accessories or software are included.

Capacity and headroom

The 8-inch ductile iron body handles typical pressures found in HVAC, water distribution, and general process piping. The lug pattern allows dead-end service with downstream piping removed. The gear operator adds operating torque headroom for larger line sizes. The valve is not suited for applications requiring automated actuation, higher pressure classes, or seat materials other than BUNA.

Questions about this item

How often does the Buna seat in the 8" T-367AB-G valve need replacement under normal service?

The Buna seat should be inspected annually and replaced if swelling, cracking or loss of elasticity is found; typical service life ranges from three to five years depending on media and temperature.

What pressure or temperature limit is reached first when the ductile iron lug body runs continuously at full rating?

The ductile iron lug body reaches its pressure class ceiling before the Buna seat hits its temperature maximum, so sustained operation is bounded by the valve's rated working pressure.

Does the gear operator on the 8" T-367AB-G generate noticeable heat or noise during all-day cycling?

The manual gear operator produces negligible heat and only light mechanical noise during cycling; no motor or actuator is present to add continuous power draw or fan sound.
