Bronze full-port valve for plumbing systems

The Nibco S-585-70 is a cast bronze ball valve designed for inline installation in residential and commercial plumbing. Its full-port bore allows unrestricted flow through 1-1/4 inch sweat connections, making it suitable for water, oil and gas lines where minimal pressure drop is required.

Two-piece bronze body with blowout-proof stem

The valve uses a two-piece bronze body sealed with PTFE and RPTFE seats rated for 600 psi CWP and 150 psi WSP. A chrome-plated brass ball and silicon bronze stem resist corrosion, while the blowout-proof stem design prevents ejection under pressure. The zinc-plated steel lever handle features a plastisol coating for grip across a -20 °F to 400 °F temperature range.

Sweat connections demand soldering skill

Sweat-by-sweat ends require copper pipe soldering, so installers need torch equipment and flux compatible with bronze. The 600 psi CWP limit restricts use in high-pressure hydronic or steam mains above 150 psi WSP. Systems exceeding 400 °F or requiring flanged, threaded or press-fit joints will need a different valve configuration.

Questions about this item

What does the 600 psi CWP rating mean for the sweat connection?

The 600 psi cold working pressure is the maximum non-shock pressure the valve can handle at room temperature when properly soldered into copper pipe.

What copper pipe size fits the sweat ends?

The valve is made for 1-1/4 inch copper tubing, so the sweat sockets accept that outside diameter directly.

How do I install the valve without damaging the RPTFE seats?

Remove the lever handle, wrap the body with a wet cloth, apply heat evenly to each sweat joint, and solder quickly so the seats stay below 400 °F.
