Detects flood events with SentryPlus Alert technology
Protects against high hazard (toxic) fluids
Lead Free Construction
Description
This 4 inch lead free ductile iron reduced pressure zone (RPZ) backflow preventer assembly provides critical protection against high hazard (toxic) fluids in industrial water services. Featuring a robust ductile iron body with patented ArmorTek epoxy coating, it offers advanced corrosion resistance. Internal stainless steel components ensure maximum performance and durability. The integrated SentryPlus Alert flood sensor detects continuous relief valve discharge and can relay alerts via BMS, cellular communication, or the Sensor Control Monitor for integration with BAS via Modbus or Wi-Fi through the Nexa platform. Item number F683142.
