Nibco NL99LX0A Bronze Ball Valve Locking Handle

Product Description

The NIBCO NL99LX0A is a three-piece bronze ball valve with a locking handle, designed for quarter-turn (90-degree) open-to-close operation. The valve features a PTFE seat ring, stainless steel ball, and stainless steel stem, providing high chemical resistance suited for demanding high-pressure applications. Threaded end connections simplify installation in new construction and retrofit work. The NIB-SEAL insulated locking handle is designed to eliminate condensate formation, making this valve well suited for chilled water and refrigeration piping systems. Licensed plumbers and pipefitters are the typical installers in commercial, mechanical, and industrial settings.

This valve is sized at 1 inch and is intended for commercial, mechanical, and industrial piping systems where a reliable shutoff with tamper-resistant locking capability is required. The threaded end configuration suits standard pipe connections across a wide range of system types. The NIB-SEAL handle option makes it particularly applicable in systems where condensate on valve bodies is a concern, such as chilled water distribution or low-temperature fluid lines.
