3-inch ductile iron lug butterfly valve with aluminum bronze disc and gear operator

Legend Valve

Legend Valve 116-643 3" T-365AB-G Butterfly Valve EPDM

SKU CH-PQ7C-6TN60

A 3-inch ductile-iron lug butterfly valve with an aluminum-bronze disc, gear operator and EPDM seat for flow control

  • 3-inch ductile iron body provides robust pipeline strength
  • Aluminium bronze disc resists corrosion for longer service life
  • Gear operated mechanism allows precise flow control with less effort
  • EPDM seat material handles water and compatible fluids reliably
  • Model 116-643 identifies the exact valve for ordering and maintenance

3-inch Lug Butterfly Valve with Gear Operator

This ductile-iron butterfly valve uses a lug body for direct bolting between pipe flanges. The aluminium-bronze disc and EPDM seat suit water and compatible fluid services. A built-in gear operator provides mechanical advantage for manual control. It is intended for installers who need a quarter-turn shut-off valve in three-inch piping systems.

Installation notes and common issues

The lug pattern lets the valve stay in line when one flange is removed, so downstream maintenance is simpler than with wafer bodies. Alignment of the bolt holes across both flanges is critical; misalignment stresses the body and can prevent the disc from sealing. Over-tightening flange bolts may distort the lugs, and the gear operator must be mounted with the handwheel accessible for future operation.

EPDM seat chemical compatibility

The EPDM liner resists water, dilute acids and many alkalines but is not suitable for oils, hydrocarbons or strong oxidisers. California Proposition 65 warnings apply because the product contains a listed chemical. Confirm fluid compatibility before specifying this valve for the intended service.

Questions about this item

How can I verify the 3" T-365AB-G butterfly valve is operating correctly after installation?

Operate the gear handle through a full open-to-close cycle; the ductile-iron lug body and aluminum-bronze disc should rotate smoothly without binding, and the EPDM seat should seal with no visible leakage at line pressure.

What components are included with the 116-643 valve and what must be purchased separately?

The box contains the complete 3" T-365AB-G lug-type butterfly valve with gear operator; mating flanges, bolts, gaskets and any required piping are not included and must be sourced separately.

Which version of the Legend Valve 116-643 should I select for my application?

Only the 3" T-365AB-G ductile-iron lug configuration with aluminum-bronze disc, gear operator and EPDM seat is offered under this part number; choose it when those exact materials and size match your system requirements.
