374A-FS
Boiler Pressure Relief Valves with Flood Sensor Kit
Series 374A-FS Boiler Pressure Relief Valves with Flood Sensor Kit are used in hot water boiler applications to protect against excessive pressure on all types of hot water heating boiler equipment. They have an iron body construction with forged bronze inlet connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. Series 374A resists corrosive water conditions, sticking and freezing, and prevents water and sediment from being trapped in the seat. It is designed for emergency safety relief and shall not be used as an operating control. Standard Pressure Setting: 30psi (206.9 kPa). Pressure range: rated up to 550,000 BTU/hr at a 30 psi (2 bar) setting only.
This series features an integrated flood sensor with SentryPlus Alert® Technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.
