Anvil 4351012240 Steam Service Ball Valve 1-1/2 in Fnpt

Product Description

The ANVIL 4351012240 is a 1-piece stainless steel steam service ball valve designed for demanding steam and high-temperature fluid applications. Built with a 316 stainless steel body and handle, it features a standard port configuration and FNPT x FNPT end connections in a 1-1/2 inch pipe size. The Graphoil seat seals are rated for steam service duty, and the locking lever handle allows the valve to be secured in the open or closed position to prevent accidental actuation. This valve is installed by licensed plumbers, steamfitters, and pipefitters in commercial and industrial piping systems.

This valve is suited for steam service lines in commercial buildings, industrial facilities, and process piping systems where 1-1/2 inch threaded connections are required. The FNPT x FNPT configuration makes it compatible with standard female-threaded pipe fittings. The standard port design provides reliable shutoff for steam, condensate, and related high-temperature media. Applications include boiler supply and return piping, steam distribution headers, and zone isolation valves in commercial steam heating systems.
