Additional Details

This 10 inch Reduced Pressure Detector Assembly Backflow Preventer is designed to prevent the reverse flow of fire protection system substances into the potable water supply due to backsiphonage or backpressure. It is ideal for continuous pressure piping applications and cross-connections identified as health hazards.

Design & Components

  • Features an epoxy coated cast iron body, domestic OSY resilient seated gate valves, and captured spring check valves.
  • Includes replaceable stainless steel seats and top mounted test cocks.
  • A pressure differential relief valve and a GPM meter are integrated to detect underground leaks and unauthorized water use.
  • The modular check design facilitates maintenance and assembly access.
  • Features an Air-in/Water-out relief valve design for maximum capacity during emergency conditions.

Corrosion Protection

  • Utilizes ArmorTek® coating technology, a patented 3-part advanced epoxy system, designed to resist both microbial-induced corrosion (MIC) and exposed metal substrate corrosion on internal components.

Flood Detection & Alerts

  • Equipped with a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
  • When activated via an add-on sensor connection kit (sold separately), the sensor relays a signal for notification of potential flooding to service personnel.
  • The flood alerts are compatible with Building Management Systems (BMS) and cellular network communication.

FAQs

What is the primary purpose of this backflow preventer?

This 10-inch Reduced Pressure Detector Assembly (RPDA) backflow preventer is designed to prevent the reverse flow of fire protection system substances, such as glycerin or stagnant water, into the potable water supply. It protects against backsiphonage and backpressure in health hazard applications.

What type of corrosion protection does this assembly offer?

The assembly features ArmorTek® coating technology, a patented three-part advanced epoxy system applied to the cast iron body's internal and external surfaces. This coating is engineered to resist both microbial-induced corrosion (MIC) and general exposed metal substrate corrosion.

How does the integrated flood sensor work?

The flood sensor with SentryPlus Alert® technology detects excessive water discharges from the relief valve. When activated via an add-on sensor connection kit (sold separately), the sensor relays a signal to facility personnel or building management systems to notify them of potential flooding.

What are the key components included in this backflow assembly?

This backflow preventer includes an epoxy coated cast iron body, domestic OSY resilient seated gate valves, captured spring check valves, replaceable stainless steel seats, top mounted test cocks, a pressure differential relief valve, and a GPM (gallons per minute) meter.

What are the operating pressure and temperature limits for this unit?

This backflow preventer has a maximum working pressure of 175 psi (12.1 bar). It can operate continuously within a temperature range of 33°F to 140°F (0.5°C to 60°C).
