WATTS® 9217 2453818

WATTS® Regulators Series LF25AUB-Z3 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 copper silicon alloy body construction, union inlet connection, integral stainless steel strainer and high-temperature-resistant reinforced diaphragm for hot water. The Series LF25AUB-Z3 is available with a variety of end connections including - threaded, solder, PEX, quick-connect and CPVC with both union and double union connections. Series LF25AUB-Z3 has an adjustable pressure range and is serviceable in-line. 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.
