Watts 0009309 Valve

The Watts 0009309 (Model LF25AUB-Z3) is a contractor-grade 1-inch lead free water pressure reducing valve designed for rigorous commercial and residential demand. Built with a heavy-duty lead free brass body, this PRV protects downstream plumbing components by stabilizing fluctuating supply pressures up to 300 psi. It features a standard pressure range of 25 to 75 psi, factory-preset at 50 psi, allowing for precise field adjustments. The Z3 sealed spring cage and stainless steel adjustment screws make this unit ideal for pit installations or outdoor environments where corrosion resistance is paramount.

This model is a 1-to-1 drop-in replacement for 25AUBZ3-1, LF25AUB-LP-Z3-1, and LF25AUB-Z3-1, ensuring seamless HVACR and plumbing system compatibility. It integrates a stainless steel strainer and a high-temperature reinforced diaphragm capable of handling water up to 180°F. The bypass feature effectively manages thermal expansion pressure, preventing unnecessary stress on the system. For efficient maintenance, the valve is fully serviceable in-line, featuring a replaceable seat module that eliminates the need for total unit removal during routine repairs.
