The Watts 3 LFN223FM2-S Valve, 3" Flanged Inlet x Flanged Outlet Water Pressure Reducing w/Strainer- Lead Freee can handle pressures up to 175 psi and may be adjusted from 25-75 psi with a standard setting at 50 psi.  This item is used to decrease the incoming water pressure to protect your plumbing components and also conserve water by reducing pressure without changing the flow of water. All parts in this valve are able to be serviced without removing from the main line.

Since 1874, the Watts Water Technologies has built upon their water technologies to provide efficient conservation of water in commercial, residential, industrial and municipal applications.  In the early 1900’s, Watts introduced the revolutionary combination of temperature and pressure relief valves.  This prevented hot water heaters from exploding.  Today this technology continues to be a necessary part in every water heating system.
