The 2" 4000B RP Backflow Preventer Valve protects your main water supply lines from cross-contamination by stopping backflow in commercial, industrial, and residential fire protection systems. This reduced pressure principle assembly isolates potable water supplies using a differential pressure relief valve while keeping flow efficiency high.

This assembly meets code requirements under NFPA 13 and NFPA 25 for fire protection service and testing. It carries UL 312 listings for potable water systems, FM Approvals, and ASSE 1013 standards for backflow prevention reliability.

  • ASTM A536 Ductile Iron Body: Resists mechanical stress and corrosion in demanding environments.
  • 300-Series Stainless Steel Internals: Prevents rust on springs and fasteners to extend maintenance intervals.
  • Reversible and Replaceable EPDM Seats: Minimizes leakage with high-strength thermoplastic check valves.
  • Reduced Pressure Design: Minimizes pressure loss compared to traditional backflow preventers.
  • AWWA C606 Grooved Ends: Supports horizontal and vertical installation with upward flow.
  • Operational Parameters: Handles working pressures up to 175 PSI across a temperature range of 33°F to 140°F.
