Watts 1.5 S1115,150 1-1/2" Pressure Reducing Valve, Ductile Iron, Flanged

The Watts 1.5 S1115,150 is a 1-1/2" angle-pattern pilot-operated pressure reducing control valve with Flanged connections. It features a ductile iron body. Rated to 200 psi.

This 1 1/2 inch stainless steel class 150 flanged pressure reducing automatic control valve is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates. The valve has an adjustable set-point range of 20-200 psig. 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.
