About the Watts 1/2 LFN45BM1 Valve, 1/2" Pressure Reducing Valve Brass MPT x FPT - Lead Free

Series LFN45B Lead Free* Water Pressure Reducing Valves are used in commercial and residential applications to reduce incoming water pressure for protection of plumbing system components and to reduce water consumption. It consists of a Lead Free* cast copper silicon alloy body construction, stainless steel integral strainer, thermoplastic seat and cage, thermal expansion bypass, and sealed spring cage for waterworks pit installations. The LFN45B Series is available in a variety of end connections including: threaded, solder, PEX, quick-connect and CPVC with both union and double union connections. Maximum Working Pressure: 400psi (27.6 bar), Adjustable Reduced Pressure Range: 25 to 75psi (172 to 517 kPa), Standard Pressure Setting: 50psi (345 kPa).

SERIES LFN45B-M1 Water Pressure Reducing Valves are designed to reduce incoming water pressure to a sensible level to protect plumbing system components and reduce water consumption. The LFN45B features Lead Free* construction to comply with Lead Free* installation requirements. This series is suitable for water supply pressures up to 400psi (27.6 bar) and may be adjusted from 25 – 75psi (172 – 517 kPa). The standard setting is 50psi (345 kPa). All parts are quickly and easily serviceable without removing the valve from the line. The standard bypass feature permits the flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply.
