Series LFN223B super capacity 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 LFN223B features lead-free construction to comply with Lead-free installation requirements. This series is suitable for water supply pressures up to 300 psi and may be adjusted from 25 - 75 psi. The standard setting is 50 psi. Series LFN223B features an enlarged diaphragm, spring cage and seat orifice for super capacity performance. 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.
