Watts 3 116FM Relief Valve, Ductile Iron, Flanged

The Watts 3 116FM is a 3" globe-pattern pilot-operated pressure relief / sustaining / backpressure control valve with Flanged connections. It features a ductile iron body.

This 3 inch fire pump suction control valve, model 116-1FM, is designed to permit flow when upstream suction pressure is above the adjustable set point of the control pilot, and throttle toward closed when upstream suction pressure falls below the adjustable set point. The valve is installed downstream of the fire pump, and senses pump suction pressure through a field installed pilot sensing line. 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.
