Lead-Free Pressure Reducing Valve

The Watts LFN55BM1-U reduces incoming water pressure to a preset 50 psi for residential and light-commercial plumbing systems. It is built from a lead-free copper silicon alloy that meets safe-drinking-water requirements. The valve accepts 1-inch NPT union by FNPT connections and includes an integral strainer to catch debris.

Adjustable Range 25 to 75 psi

Outlet pressure can be set anywhere between 25 and 75 psi to match local code or fixture needs. The single adjustment point determines whether the valve suits a specific installation, so verify the required pressure before purchase. No other spring kits or cartridges are supplied or referenced.

Rated for 180 °F and 400 psi

Maximum working temperature is 180 degrees Fahrenheit and maximum supply pressure is 400 psi. The bronze body and stainless-steel internals handle continuous duty without external cooling or power. Installations above these limits or in steam service are not supported by this model.
