1-1/2" FNPT Swing Check Valve

This brass swing check valve uses a 1-1/2 inch FNPT connection to prevent backflow in water and steam lines. It suits installers who need a simple inline device for horizontal or vertical pipe runs.

200 psi water and 125 psi steam limits

The valve handles water pressure up to 200 psi and steam pressure up to 125 psi WSP. Operating temperature ranges from -20 degrees F to 180 degrees F, so it cannot serve high-temperature steam systems beyond that ceiling.

76 gpm full-flow capacity

A cracking pressure between 0.750 and 1.000 psi opens the brass disc to deliver 76 gpm at full flow. Buyers who need a higher flow rate or a lower cracking pressure for gravity-fed circuits must choose a different valve.

Questions about this item

Should I choose the 1 1/2" FNPT version with 76 gpm flow or a different size for my plumbing system?

Select the 1 1/2" FNPT version when your piping matches that exact nominal size and thread type; the 76 gpm rating indicates the maximum flow capacity this specific valve body can pass without restriction.

What does the 76 gpm flow rating mean once the valve is installed in a real piping system?

The 76 gpm figure represents the full-flow capacity through the brass swing-check mechanism; actual flow will depend on your system pressure, pipe length, and any upstream restrictions.

How does the FNPT connection standard limit the pressure or temperature I can run through this valve?

The FNPT threads seal with taper engagement and thread sealant; the valve body itself is rated for 200 psi water at 180 °F and 125 psi steam, so the connection does not lower those limits.
