Honeywell has launched its BA295 series of compact backflow preventers,which ensure contaminated water cannot flow back into the public mains supply.
The BA295 series,which uses the PPZ principle,protects drinking water systems against back pressure,back flow and back syphonage, ensuring compliance with relevant water regulations.
The valves can be used for residential buildings,as well as industrial and commercial purposes.Fluids up to and including liquid category 4 (toxic, very toxic, carcinogenic and radioactive substances)to EN 1717 are protected.This corresponds to construction type 2 to EN 1717.
The valves provide a neat and cost-effective alternative to providing an air gap to isolate water systems. They feature a triple security to provide optimum protection against back pressure and back siphonage - two check valves and a discharge valve divide the unit into three chambers, each providing a separate pressure zone.
Maintenance is simple,as there is unrestricted access to all internal
components.
