Lead-Free Brass Pressure Reducing Valve

The Watts 2 LF 25AUBZ3 reduces incoming water pressure to a preset 50 psi. It is designed for residential or commercial plumbing systems that require safe, lead-free components. The valve body is constructed from lead-free brass for durability and regulatory compliance. An integral strainer helps protect downstream fixtures from debris.

Verify Pipe Size Connection And Pressure Range

Confirm the existing supply line uses a 2-inch FNPT union connection before ordering. The adjustment range spans 25 to 75 psi, so ensure this covers the required outlet pressure. The valve is rated for a maximum inlet pressure of 300 psi and a maximum temperature of 160 degrees Fahrenheit. Installation must meet applicable local codes and the listed standards.

Thermal And Pressure Limits In Normal Use

During normal operation the valve handles water temperatures up to 160 degrees Fahrenheit. The brass body dissipates heat from the water stream without external cooling. No moving parts generate audible noise beyond typical water flow sounds. The unit contains no electrical components, so it draws no power and imposes no electrical load on the building.

Questions about this item

Does the valve come with the union connections and strainer installed, or do I need to buy those parts separately?

The unit ships with a built-in strainer and FNPT union ends on both sides, so no extra fittings or strainer components are required for installation.

Should I choose a different pressure range if my supply pressure is higher than 75 psi?

The adjustment range is 25 to 75 psi with a 50 psi factory preset; if your supply pressure exceeds 300 psi you need a different valve, but within that limit the same model covers the range.

What does the 300 psi maximum pressure rating mean for daily use in a building supply line?

It is the highest inlet pressure the valve body can safely withstand; normal municipal supply is well below that, so the valve will regulate down to your set point without risk of body failure.
