Anvil 4351011400 Steam Service Ball Valve 0.5 in Fnpt

Product Description

The ANVIL 4351011400 is a 1-piece manual ball valve engineered for steam service applications. The carbon steel body handles working pressures up to 2000 psi, making it suitable for demanding industrial and commercial steam systems. The standard port design uses FNPT x FNPT end connections conforming to ASME B1.20.1. A locking lever handle provides positive shutoff and prevents accidental operation in high-pressure service environments. The valve seats are Nova material with Graphoil seals, a combination selected for elevated-temperature steam compatibility. Licensed plumbers, pipefitters, and steam system mechanics are the primary installers of this valve.

This valve is designed for 1/2 inch pipe steam service lines in commercial and industrial settings. Typical applications include steam distribution headers, branch isolation, and equipment shutoff on systems operating at pressures up to 2000 psi. The FNPT x FNPT end connections allow direct threaded installation into standard NPT piping without adapters. The locking lever handle is particularly useful in environments where inadvertent valve actuation must be prevented.

Compatibility

Designed as an OEM-style replacement or new-installation ball valve for 1/2 inch NPT steam service piping systems rated to 2000 psi.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes, including ASME B31.1 for power piping where applicable. Depressurize and cool the steam system fully before removing or installing any valve. Apply appropriate thread sealant rated for steam service to all FNPT connections. Verify that system operating pressure and temperature do not exceed the valve rating before returning the line to service.
