  • TypeOther

Two-Piece Bronze Ball Valve

The Nibco 58570 is a manual two-way ball valve built for inline installation in residential or light-commercial plumbing systems. Its bronze body and chrome-plated brass ball suit air, water and steam service in a straight, full-port layout.

600 psi Operating Pressure Rating

The valve handles up to 600 psi for general media and 150 psi for steam, so it matches piping systems designed around those limits. Exceeding either figure risks seal failure or body damage.

1-1/4" FNPT End Connections

Female NPT threads on both ends accept matching male pipe or adapters without soldering, freeing the installer from flame work and allowing quick removal for maintenance. The lever handle provides clear open-closed indication in tight mechanical rooms.

Questions about this item

What does the 600 psi operating pressure mean once the valve is installed in my system?

It is the maximum non-shock pressure the bronze body and chrome-plated brass ball can handle at room temperature for air or water service.

How does the FNPT connection limit what I can thread onto this valve?

The 1-1/4 inch female NPT threads accept male NPT pipe or fittings only; they will not seal on BSP, compression or flare ends without an adapter.

What clearance does the lever handle need to swing from open to closed?

The lever extends from the stem centreline, so allow a radius equal to the handle length plus a small margin for grip.
