Anvil 4351012180 Steam Service Ball Valve 3/4 in Fnpt

Product Description

The ANVIL 4351012180 is a 1-piece stainless steel manual ball valve rated for steam service applications. The valve features an FNPT x FNPT end connection in a 3/4-inch pipe size and operates through a locking lever handle, providing a secure, tamper-resistant shutoff in high-temperature and high-pressure environments. The body and handle are both constructed from 316 stainless steel, offering strong corrosion resistance. Graphoil seals and Nova seat material are specified for compatibility with steam media. Licensed plumbers and pipefitters are the primary installers for this type of valve in commercial and industrial steam systems.

This valve is suited for steam distribution lines, process piping, and mechanical room applications where a reliable manual isolation point is required. The standard port configuration supports consistent flow characteristics in 3/4-inch steam service lines. The locking lever handle prevents accidental actuation in environments where inadvertent valve movement could cause safety or process issues. It is commonly specified in commercial buildings, industrial facilities, and institutional steam heating systems where stainless steel construction is required for media compatibility or code compliance.

Compatibility

Designed as an OEM-style replacement or new-installation valve for 3/4-inch threaded steam service piping systems requiring a standard port ball valve with FNPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including ASME and local steam piping requirements. Shut down and depressurize the steam system completely and allow it to cool before removing any existing valve or fitting. Ensure thread engagement and sealant compatibility with steam service before pressurizing the line. Do not over-torque threaded fittings, and verify all connections are leak-free before returning the system to service.
