12-Inch Lug Butterfly Valve

This 12-inch lug-type butterfly valve is built for plumbing systems that require reliable flow control. The ductile iron body provides structural strength for industrial and commercial piping. Gear operation allows precise manual adjustment without excessive force. It suits installers who need a durable quarter-turn valve for water or compatible fluids.

Ductile Iron Body with Aluminum Bronze Disc

The lug pattern enables direct bolting to mating flanges for secure mounting in-line. An aluminum bronze disc resists corrosion and wear in demanding fluid environments. Buna seat material offers compatible sealing for many water-based applications. The gear operator simplifies daily actuation and reduces operator fatigue during frequent use.

Gear-Operated Flow Control

Gear drive delivers smooth torque transfer for consistent opening and closing under normal system pressure. Mechanical operation eliminates the need for external power or pneumatic supply. Buna seating maintains seal integrity across typical temperature ranges encountered in plumbing service. California Proposition 65 warnings apply for chemical exposure awareness.

Questions about this item

What size pipe does the 12 inch lug-type butterfly valve fit?

The valve is built for 12 inch nominal pipe and bolts between matching flanges using the lug pattern on the ductile iron body.

What clearance and hardware are needed to mount the gear-operated unit?

The ductile iron body with aluminum bronze disc requires flange gaskets, studs or bolts sized for the lug holes, and enough axial space for the gear operator housing.

How is the gear operator installed and what common step is missed?

The gear operator ships mounted on the valve stem; the step often missed is verifying the handwheel turns the disc fully open and shut before pressurising the line.
