Nibco NL944K6P Fire Safe Ball Valve 1/2 Inch Fnpt

Product Description

The NIBCO NL944K6P is a 1-piece, fire-safe manual ball valve designed for high-pressure fluid control in commercial and industrial piping systems. Built with a bronze and carbon steel body and stainless steel trim, it handles working pressures up to 2000 psi and temperatures up to 400 degrees F. The reduced-port design uses a reinforced PTFE seat for reliable shutoff and long service life. A locking lever handle prevents accidental actuation in critical service lines. This valve is compliant with MSS SP-110 standards and is installed by licensed plumbers and pipefitters in demanding applications.

The NL944K6P is suited for commercial plumbing, fire protection-adjacent piping, and industrial process lines where fire-safe shutoff valves are required. Its FNPT x FNPT end connections allow straightforward threaded installation in half-inch pipe runs. The locking lever adds a layer of safety in facilities where inadvertent valve operation poses a risk. This valve is appropriate for both new construction and retrofit service in systems requiring verified fire-safe certification and high-pressure ratings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Depressurize and drain the line completely before removing any existing valve or fitting. Apply appropriate thread sealant to FNPT connections per the system fluid and pressure requirements. Verify that the locking lever is secured in the desired position after installation and that the valve is accessible for future operation and inspection.
