Nibco NL944K8P Fire Safe Ball Valve 3/4 Inch Fnpt

Product Description

The NIBCO NL944K8P is a fire safe manual ball valve designed for industrial and commercial piping systems where high-pressure shutoff capability is required. This 1-piece bronze and carbon steel body valve features a reduced port design with FNPT x FNPT end connections and a locking lever handle for positive, tamper-resistant shutoff. It is rated to 2000 psi maximum working pressure and withstands temperatures up to 400 degrees F. The reinforced PTFE seat and stainless steel trim contribute to reliable sealing performance in demanding service environments. Licensed plumbers and pipefitters are the primary installers of this valve type.

This valve is suited for use in commercial and industrial mechanical systems where fire-safe shutoff valves are specified or required by code. Its locking lever handle makes it appropriate for applications where accidental operation must be prevented, such as fuel gas, hydraulic, or compressed-air lines. The FNPT x FNPT end connections allow direct threaded installation into standard female pipe thread ports on 3/4 inch pipe systems. It meets MSS SP-110 requirements, making it a code-acceptable choice where that standard is cited in project specifications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Shut off and depressurize the system fully before removing any existing valve or making threaded connections. Use appropriate thread sealant or tape rated for the service fluid and pressure when making FNPT connections. Do not exceed the rated working pressure or temperature listed on this valve.
