Full-Port Bronze Ball Valve

The Nibco T-585-70-66 is a 1/2-inch inline ball valve built for residential and light-commercial plumbing. Its bronze body and 316 stainless-steel ball suit water, oil and gas lines. A blowout-proof stem and RPTFE seats provide reliable shut-off for installers and maintenance crews.

Pressure and Temperature Limits

The valve handles 600 psi cold working pressure and 150 psi saturated steam pressure. Operating temperatures range from -20 to 400 degrees F. FNPT threaded ends connect directly to standard iron or steel pipe without adapters.

Upgrade from Standard-Port Valves

Full-port design eliminates the flow restriction found in reduced-port models, lowering pressure drop across the fitting. The quarter-turn lever with plastisol-coated grip speeds up operation compared to multi-turn gate valves. Not suited for applications requiring automated actuation or pressures above the rated limits.

Questions about this item

Which size and port style should I pick for a half-inch line that needs full flow?

The valve is a 1/2 inch full port model so the bore matches the pipe diameter and does not restrict flow.

What does the 600 psi CWP rating mean when the valve is installed on a water system?

It indicates the maximum cold water pressure the valve can handle continuously at ambient temperature.

How does the FNPT x FNPT connection affect the pressure limit in steam service?

The threaded ends are rated for 150 psi WSP so steam pressure must stay at or below that figure.
