Series LF25AUB-Z3 Lead Free* Water Pressure Reducing Valves are used in commercial and residential applications to reduce incoming water pressure to a predetermined level, thereby protecting downstream plumbing system components and reducing water consumption. For versatility, a variety of end connections are available: threaded, solder, PEX, quick-connect, CPVC, Press, or Cold Expansion PEX (ASTM F1960) with union and double union. Standard pressure setting is 50psi with an adjustable range of 25 ‒ 75psi (172 ‒ 517 kPa). For sizes: 1/2 to 2 IN (15 ‒ 50mm). Temperature range is 33 to 180 degrees F (0.5 to 82 degrees C).
