Anvil 4351012120 Steam Service Ball Valve 1/4 in Fnpt

Product Description

The ANVIL 4351012120 is a 1-piece stainless steel manual ball valve engineered for steam service applications. The body and handle are constructed from 316 stainless steel, providing corrosion resistance in demanding thermal and chemical environments. A Graphoil seal and Nova seat material are specified for steam compatibility, allowing this valve to perform reliably where standard ball valves would fail. The standard-port design and FNPT x FNPT end connections allow straightforward inline installation. Licensed plumbers and pipefitters install this valve in steam distribution, condensate return, and process piping systems where positive shutoff is required.

This valve is suited for residential and commercial steam heating systems as well as light industrial process lines. The locking lever handle allows the operator to secure the valve in the open or closed position, reducing the risk of accidental actuation in high-traffic mechanical rooms or process environments. The FNPT x FNPT connections fit standard threaded pipe in 1/4 inch pipe size, making it compatible with common branch and isolation piping configurations found in boiler rooms and mechanical systems.

Key Features

• 316 stainless steel body and handle for corrosion resistance in steam service
• Graphoil seal material rated for high-temperature steam applications
• Nova seat material designed for steam compatibility
• Locking lever handle prevents accidental valve position changes
• 1-piece body construction for compact inline installation

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for threaded steam service piping systems using 1/4 inch pipe with female NPT connections.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes such as the IFGC or local steam piping standards. Depressurize and isolate the steam line completely before removing any existing valve or fitting. Apply thread sealant rated for steam service to all NPT connections. Do not overtighten threaded connections; follow standard trade practice for the pipe size and material.
