|Model:||AI-903 DZR Double Check Valve (Compression)|
|Last Updated:||24 Mar 2017|
The Altecnic range of double check valves is used to prevent the risk of backflow and back siphonage contamination in domestic dwellings, public and commercial buildings.
The smaller sizes should be installed close to the water outlet such as taps, basin taps, showers and toilets to prevent back siphonage contamination to the water supply, should a mains supply pipe burst.
The larger sizes are installed in the main cold water supply inside public and commercial buildings.
Altecnic double check valves comply with BS EN 13959 ‘Anti- pollution check valves’ family E, type D - non controllable.
The Altecnic non verifiable double check valves are manufactured from DZR copper alloy with a chrome plated finish, to enhance the appearance for exposed installations.
The valves provide category 3 protection for both backflow and back siphonage as specified in the Water Supply (Water Fittings) Regulations 1999.
Supplied with an integral test point for monitoring the function of the downstream check valve.
The valves are designed for high flow rates with minimum pressure drops.
Supplied with compression ends complying with BS EN 1252-2 for use with R250 (half hard) copper tube.
