Reduced Pressure Zone (RPZ) Backflow Preventers

A reduced pressure zone (RPZ) valve is one of the safest and most reliable backflow preventer valves available. RPZ valves offer protection against back pressure and siphonage in order to protect the mains water supply and drinking network from contamination, particularly in significant hazard applications in which the consequence of backflow into water supply could cause significant health issues. RPZ valves have two check valves inside with a pressure chamber inside within which the pressure is kept lower than the pressure of the water in the system. If reduced pressure occurs in the rest of the water system, the RPZ valve opens and allows contaminated water to leave the system rather than contaminating the drinking water supply. • Incorporates a double check valve with a reduced pressure zone for protection against back pressure and back siphonage

• Protection against fluid category 4: Type BA Verifiable backflow preventer with reduced pressure zone
• All serviceable components can be reached within easy access
