Watts LF223 Lead Free Water Pressure Reducing Valve

Description:

The Watts LF223 3/4" Valve is a lead-free high-capacity water pressure reducing valve designed to reduce incoming water pressure to a safe, preset level to protect downstream plumbing components and reduce water consumption. It features an adjustable pressure range of 25–75 PSI with a factory preset of 50 PSI and is commonly used in residential, commercial, and industrial potable water distribution systems. The valve is serviceable in-line and is engineered for reliable pressure control under varying supply conditions.

Applications:

The LF223 is widely installed on building water service entrances, commercial plumbing systems, apartment complexes, schools, hospitals, industrial facilities, irrigation systems, and municipal water distribution networks. It maintains a consistent downstream pressure, helping protect fixtures, appliances, piping, and valves from excessive supply pressure while improving water efficiency and reducing wear on plumbing components.
