Lead Free Pressure Reducing Valve

This Watts valve reduces incoming water pressure to a preset 50 psi and can be adjusted between 25 and 75 psi. It fits 3/4 inch FNPT connections and is constructed from lead free bronze. The unit meets ASSE 1003, ANSI A 112.26, and CSA B356 standards. It is designed for residential and commercial plumbing systems.

Integrated Strainer and EZ Adjustment

A built in strainer traps debris before it reaches the valve seat, reducing maintenance and extending service life. The EZ adjustment mechanism allows pressure changes without special tools. These features simplify installation and ongoing upkeep for the installer.

Capacity and Pressure Headroom

The valve handles a maximum inlet pressure of 400 psi and water temperatures up to 180 degrees F. It comfortably protects downstream fixtures within the 25 to 75 psi adjustment range. Systems requiring pressure settings above 75 psi or temperatures exceeding 180 degrees F will need a different solution.

Questions about this item

Does the built-in strainer on the LFN45BM1-DU-EZ need periodic cleaning and how often?

The valve includes a strainer that should be inspected and cleaned periodically to maintain flow; frequency depends on local water quality and debris levels.

What is the maximum inlet pressure the bronze body and FNPT connections can handle continuously?

The valve is rated for a maximum pressure of 400 psi, which is the limit the bronze body and FNPT connections can sustain.

How hot does the valve body get when supply water reaches the 180 °F maximum temperature rating?

At the 180 °F maximum temperature rating the bronze body will approach the water temperature, so expect hot surfaces during extended high-temperature operation.
