Flood Sensor Connectivity
The integrated SentryPlus Alert® flood sensor can be paired with an add-on connection kit for enhanced monitoring.
Connection kit options allow for integration with Building Automation Systems (BAS) via RS‑485 Modbus or the Nexa® platform through Wi-Fi, as well as cellular communication and BMS.
This 3 inch lead free MasterSeries® configurable reduced pressure zone backflow preventer assembly is designed to help protect against high hazard (toxic) fluids in water services for industrial installations and applications.
The assembly consists of an epoxy coated ductile iron body, domestic outside stem and yoke resilient seated gate valves, test cocks, spring loaded check valves, and a pressure differential relief valve.
Advanced Corrosion Resistance
The ductile iron body is fused with patented 3-part ArmorTek® epoxy coating for advanced corrosion resistance, specifically designed to limit both microbial induced (MIC) and exposed metal substrate corrosion.
Enhanced Durability & Performance
Improved with a stainless-steel relief valve seat and stainless-steel check components for maximum performance, greater dependability, and extended valve life.
Features stainless steel springs.
The relief valve is field reversible.
Integrated Flood Monitoring
This backflow assembly contains a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
When paired with an add-on connection kit, the sensor is activated to relay alerts for potential flooding events.
Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS‑485 Modbus or the Nexa® platform through Wi-Fi.
Design & Construction
Lead free construction ensures compliance with safety standards.
What is the primary purpose of this backflow preventer?
This backflow preventer assembly is designed to protect water services in industrial installations and applications from high hazard (toxic) fluids by preventing backflow into the potable water supply.
What are the benefits of the ArmorTek® coating?
The patented 3-part ArmorTek® epoxy coating on the ductile iron body provides advanced corrosion resistance, specifically designed to limit microbial induced corrosion (MIC) and protect exposed metal substrates, extending the life of the assembly.
How does the SentryPlus Alert® flood sensor work?
The SentryPlus Alert® flood sensor detects continuous or excessive water discharge from the relief valve. When paired with an optional connection kit, it can relay alerts for potential flooding events, improving system safety.
Is this backflow preventer suitable for all types of installations?
This model features a configurable N-Pattern design, offering flexibility to adapt to various piping layouts and installation requirements in industrial settings.
What materials are used for the critical internal components?
It utilizes a stainless-steel relief valve seat and stainless-steel check components, along with stainless steel springs, to ensure maximum performance, durability, and a prolonged valve life.
