Watts 005984 Lead Free Pressure Reducing Valve

The Watts LP U5B-LP-Z3 1/2" Pressure Reducing Valve (Part No. 005984) is a lead-free, inline water pressure regulator that automatically reduces incoming potable water pressure to a safe, controlled level to protect downstream piping, fittings, and appliances. Built with a lead-free cast copper-silicon alloy body and an integral stainless steel strainer, it delivers reliable long‑term operation and can be serviced in-line without removing the valve from the pipe. A thermal expansion bypass feature helps prevent water hammer, supporting overall system efficiency, and the unit is suitable for hot or cold potable water applications. Technical specifications include: Model U5B-LP-Z3 / LFU5B-LP-Z3, 1/2" FNPT union × FNPT connections, pressure adjustment range 10–35 PSI (factory setting 30 PSI), maximum working pressure 300 PSI, maximum operating temperature 160°F (71°C), and service media of potable water. This valve is commonly installed on municipal service entrances, commercial buildings, apartment complexes, irrigation systems, schools, hospitals, manufacturing facilities, and residential plumbing systems, where maintaining downstream pressure amid supply fluctuations helps prevent water hammer and protects valves, fixtures, and equipment.
