3-Inch Lug Butterfly Valve

This lug-style butterfly valve controls flow in piping systems with a 3-inch nominal bore. The cast iron body and ductile iron disc suit industrial water and compatible fluid service. A lever handle provides manual quarter-turn operation for quick isolation or throttling.

FKM Viton Liner Benefits

The FKM liner resists a broad range of chemicals and withstands temperatures from minus 20 to 300 degrees Fahrenheit. This material choice extends service life in applications where standard elastomers would degrade or swell. The liner also ensures a tight seal against the disc throughout the stated pressure range.

200 PSI Pressure Limit

The valve is rated for a maximum water pressure of 200 psi at the published temperature extremes. Exceeding this pressure risks body or disc deformation and liner extrusion. The four-bolt lug pattern on a 6-inch bolt circle requires matching flanges and proper bolt torque to maintain the rated seal.

Questions about this item

How often will the Viton liner need replacement in a 300 °F application?

The FKM liner is rated for the full -20 to 300 °F range, so replacement depends on media and cycling rather than temperature alone.

What pressure limit is reached first during continuous operation?

The valve is rated for 200 psi maximum water pressure, which is the primary limit under sustained use.

How much heat does the cast iron body radiate when the valve runs all day at 300 °F?

Cast iron conducts heat steadily; at the top of the 300 °F range the body will be very hot to touch, so insulation or guarding is advised.
