Watts® LF223 Pressure Reducing Valve, High Capacity, 1 Inch, FNPT, 300 psi, Media: Water, Brass Body, Zinc Plated Wire Spring, Stainless Steel Seat, Copper Silicone Alloy Disc Holder, Buna-N Bottom Plug Gasket/Seat Gasket/O-Ring, Buna-N Diaphragm, 33 - 160 deg F, 10-15/16 Inch W x 8-5/8 Inch H

Series LF223 and LF223S high-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 LF223/LF223S features lead-free construction to comply with lead-free installation requirements. This series is suitable for water supply pressures up to 300 psi (20.7 bar) and may be adjusted from 25 – 75 psi (172 – 517 kPa). The standard setting is 50 psi (345 kPa). Series LF223 features an enlarged diaphragm, spring cage and seat orifice for high-capacity performance. Series LF223S has the same options as the LF223, except it is furnished with a strainer. All parts are quickly and easily serviceable without removing the valve from the line. The optional 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.
