Watts 2 S115,150 Pressure Reducing Valve, Ductile Iron, Flanged

The Watts 2 S115,150 is a 2" globe-pattern pilot-operated pressure reducing control valve with Flanged connections. It features a ductile iron body. Rated to 250 psi.

The 2 inch S115 150 ACV pressure reducing control valve is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates. The pressure reducing control pilot is normally open, held open by an adjustable spring setting to maintain a constant outlet pressure to the main valve. SentryPlus Alert® technology provides intelligent pressure monitoring and notifications using integrated sensors, and integrates with the Sensor Control Monitor to deliver maintenance alerts through BAS via RS-485 Modbus or the Nexa® platform over Wi-Fi.
