2 1/2 in Cast Iron Butterfly Valve

This 2 1/2 inch wafer-style butterfly valve uses a cast iron body with a ductile iron disc and Buna-N liner. A lever handle provides manual on-off control for water service. The unit carries an ABS standard listing and is rated for a maximum water pressure of 200 psi. Operating temperature range spans 10 to 180 degrees Fahrenheit.

Suited for low-pressure water isolation

This valve suits installers who need a compact wafer body that fits between standard flanges with two bolt holes on a 5 1/2 inch bolt circle and 5/8-11 lug threads. It is not for buyers who require a lugged body for dead-end service, a gear operator for high-torque applications, or a liner material rated above 180 degrees Fahrenheit.

Simple flange insertion with lever operation

Installation consists of centering the wafer between mating flanges, inserting two bolts through the aligned holes, and tightening to the specified pattern. The lever handle locks in open or closed positions. The most common issue is over-tightening flange bolts, which can distort the cast iron body and prevent the disc from sealing properly against the Buna-N liner.

Questions about this item

What pipe size and bolt pattern must my existing flange match for this 2 1/2 in wafer valve to fit?

The valve fits a 2 1/2 in pipe size with a 5 1/2 in bolt circle and two 5/8-11 lug holes.

Will the Buna-N liner and ductile-iron disc hold up against the 180 °F water I already run through my older cast-iron piping?

Yes, the Buna-N liner is rated from 10 to 180 °F and the ductile-iron disc handles the same range, matching typical hot-water lines.

How can I verify the lever-operated disc is sealing correctly after I bolt the valve between flanges?

Pressurise the line up to 200 psi and inspect the wafer faces; no visible leakage means the disc is seated properly.
