The Watts LFN45BM1-U is a 1-inch lead-free water pressure reducing valve engineered for commercial, industrial, and residential plumbing systems. It features a rugged cast copper silicon alloy body and an integral stainless steel strainer that protects internal components from sediment and debris. This valve is designed to reduce high incoming water pressure to a stable 25–75 psi range, helping to prevent pipe damage and reduce overall water consumption. The assembly includes a thermal expansion bypass and a sealed spring cage, making it suitable for both indoor and accessible outdoor or pit installations. Its serviceable in-line design allows for quick maintenance of the thermoplastic seat and cage without removing the valve from the piping.
