Watts N223B Three Inch Water Pressure Regulator

Description:

The Watts N223B Regulator 3" is a high-capacity water pressure reducing valve designed to automatically reduce and regulate incoming water pressure to a safe, consistent downstream level. Featuring a standard adjustable pressure range of 25–75 PSI with a factory setting of 50 PSI, it is commonly used in commercial, industrial, and institutional water distribution systems to protect plumbing components, reduce water consumption, and maintain stable operating pressure. The valve is serviceable in-line and built for high-flow applications.

Applications:

The Watts N223B 3" Pressure Reducing Valve is widely used in municipal water systems, commercial buildings, manufacturing facilities, schools, hospitals, apartment complexes, irrigation systems, and industrial process water applications. It automatically compensates for fluctuations in supply pressure, helping prevent damage to downstream piping, fixtures, and equipment while reducing water hammer and improving overall system efficiency. Its high-capacity design makes it ideal for large-volume water distribution networks requiring reliable and consistent pressure regulation.
