Watts Series LFN55B Water Pressure Reducing Valves

Series LFN55B 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 LFN55B features Lead Free* construction to comply with Lead Free* installation requirements. This series is suitable for water supply pressures up to 300psi (20.7 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.

This 0009671 1 1/4 inch water pressure reducing valve consists of a lead free brass body construction, NPT threaded union female inlet and outlet connection, integral stainless steel strainer, thermoplastic seat, bronze sealed spring cage for accessible outdoor waterworks or pit installations and a thermal expansion bypass.
