2-inch Stainless-Steel Float Valve

This BOB R1380-2 float valve is a 2-inch FNPT component built from stainless steel with a Viton seal. It is designed for horizontal piping installations where reliable liquid-level control is required. The valve handles a maximum pressure of 100 psi and a maximum temperature of 450 degrees F. NSF compliance confirms suitability for potable-water systems.

Installers needing horizontal 2-inch FNPT mounting

The unit suits plumbers and maintenance teams fitting horizontal pipework in commercial or industrial water systems. It is not for vertical-only installations, for piping sizes other than 2 inches, or for applications exceeding 100 psi or 450 degrees F. Buyers needing a different connection type or a lower pressure rating should look at alternative valve configurations.

Straightforward threaded installation

The valve threads directly onto 2-inch FNPT pipework using the 3/8-16 rod thread for float attachment. No specialised tools are required beyond standard pipe wrenches and thread sealant. The most common issue is debris preventing a positive shut-off, so flushing the line before final tightening is recommended. Viton seal compatibility with the specific fluid should also be verified.

Questions about this item

What size FNPT connection must my tank or piping have for this 2 in float valve?

The valve has a 2 in FNPT connection, so the mating pipe or tank opening must also be 2 in FNPT.

Will the Viton seal handle the 450 °F maximum temperature rating on my existing high-temp system?

Yes, the valve is rated to 450 °F max temperature and the Viton seal is compatible with that range.

How can I verify the valve is flowing correctly after installation?

At 35 psi inlet pressure you should see about 112 gpm, and at 85 psi about 180 gpm; measure flow at a known pressure to confirm.
