Difference between RPZ and backflow preventer

In the event of siphon backflow, the pressure on the inlet side drops. The bleeder valve reacts before the differential pressure falls below 140 mbar. The check valves on the inlet and outlet sides close, bleeder valve opens.

Fluid that represents a health hazard for human beings through the presence of one or more toxic or very toxic substances or one or more radioactive, mutagenic or carcinogenic substances.

RPZ backflow preventers are based on a three-chamber system with supply pressure, medium pressure and back pressure zones. The differential pressure controllers of the protection cartridge on the inlet side and the check valve (RV) on the outlet side ensure reliability and a high level of safety.
