Watts N223B Three Inch Water Pressure Regulator

The Watts N223B 3" Water Pressure Reducing Valve is a high-capacity regulator that automatically reduces and maintains downstream pressure at a safe, steady level. It features a 25–75 PSI adjustable range with a factory setting of 50 PSI, and a 300 PSI maximum inlet pressure with a maximum operating temperature of 160°F (71°C). The bronze-bodied valve (N223B) uses 3" connections with female NPT × female NPT fittings and is designed for potable water service; it is serviceable in-line without valve removal and includes a thermal expansion bypass. The high-capacity design, with an enlarged diaphragm and seat orifice, supports increased flow for large municipal and commercial networks. Typical applications include municipal water systems, commercial buildings, manufacturing facilities, schools, hospitals, apartment complexes, irrigation systems, and industrial process water.
