Anvil 4351012140 Steam Service Ball Valve 3/8 in Fnpt

Product Description

The ANVIL 4351012140 is a 1-piece steam service manual ball valve designed for steam and high-temperature fluid control in mechanical piping systems. Built from 316 stainless steel, it accepts 3/8 inch female NPT connections on both ends and features a standard port configuration. The locking lever handle allows positive shutoff with tamper-resistant positioning, reducing unintended valve operation in active service lines. Graphoil seals provide the heat resistance and integrity required in steam applications. This valve is installed by licensed plumbers and pipefitters working on commercial and industrial steam distribution or hydronic systems.

This valve is suited for steam service lines in commercial mechanical rooms, industrial process piping, and hydronic heating systems requiring a compact, corrosion-resistant shutoff. The FNPT x FNPT end connections allow direct threaded installation into standard iron or steel pipe assemblies. The standard port design is appropriate for most steam distribution applications where full-port flow capacity is not required. The 1-piece stainless steel body keeps the assembly compact and eliminates potential leak points found in multi-piece designs.

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 3/8 inch threaded steam service piping systems using female NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. De-pressurize and fully isolate the steam line before removing any existing valve or making new connections. Apply appropriate thread sealant rated for steam service to all FNPT connections before assembly. Confirm the locking lever is secured in the intended position after installation and system pressure is restored.
