Anvil 4351011420 3/4 Inch Steam Ball Valve Fnpt Carbon Steel

Product Description

The ANVIL 4351011420 is a 1-piece carbon steel manual ball valve engineered for steam service applications. Rated to 2000 psi working pressure, it handles the high-pressure, high-temperature demands of steam systems where reliable shutoff is critical. The valve uses a locking lever handle that prevents accidental operation, a Graphoil seal for heat resistance, and a Nova seat material suited to steam service conditions. The body and handle are both carbon steel. A stainless steel finish coating provides additional corrosion resistance. Licensed plumbers and pipefitters are the primary installers in commercial and industrial steam distribution systems.

This valve is suited for steam service lines requiring a full manual shutoff at 3/4-inch pipe connections. The FNPT x FNPT end connections allow threaded installation into standard pipe runs. The standard port design maintains flow consistent with the pipe diameter. It is commonly installed in boiler rooms, process piping, and commercial HVAC steam distribution systems where positive shutoff and tamper-resistant operation are required.

Compatibility

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

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes and ASME standards. Isolate and fully depressurize the steam system and allow all lines to cool before beginning valve installation or replacement. Apply appropriate thread sealant rated for steam service to all NPT connections. Verify pressure ratings of all adjacent components match or exceed the system working pressure before returning the system to service.
