Nibco NL944KAP Fire Safe Ball Valve 1 in Reduced Port

Product Description

The NIBCO NL944KAP is a 1-piece, fire safe manual ball valve designed for 1-inch pipe in industrial and commercial piping systems. It features a stainless steel body and a reinforced PTFE seat, with a locking lever handle that allows the operator to secure the valve in the open or closed position. The reduced port configuration controls flow through a 1-inch threaded connection in applications where full-bore flow is not required. Rated to 138 bar maximum working pressure and up to 400 degrees F, this valve is built for demanding service conditions where fire-safe performance is required.

This valve is suited for use in commercial and industrial piping systems where fire-safe shutoff capability is required. FNPT x FNPT end connections make it compatible with standard female-threaded pipe runs without additional adapters. The locking lever handle is practical in environments where inadvertent valve operation must be prevented. Licensed pipefitters and mechanical contractors typically install this valve in process, utility, or HVAC piping applications that require MSS SP-110 compliant components.

Key Features

• Fire safe ball valve rated to 138 bar maximum working pressure
• Maximum working temperature of 400 degrees F
• 1-piece stainless steel body for corrosion resistance in demanding service

Compatibility

Designed as an OEM-style replacement or new-installation fire safe ball valve for 1-inch FNPT-threaded piping systems requiring MSS SP-110 compliant components.

Installation Notes

Installation should be performed by a licensed pipefitter or qualified mechanical contractor in accordance with applicable codes, including ASME B31 piping standards. Depressurize and isolate the system completely before removing any existing valve or fitting. Apply appropriate thread sealant to FNPT connections per the sealant manufacturer and project specifications. Confirm flow direction and locking lever orientation before returning the system to service.
