15 mm 132 Low Loss Double Check Valve c/w SU

Double Check Valves (ED device) with DZR brass valve bodies suitable for most pipe materials. Flat-faced connectors allow direct connection to the pipe without the need for sealants or additional adapters. Oversize, high-flow Cartridges provide exceptionally low head-loss characteristics. E.g. pressure drop for the 15 mm valve at 3 m/s pipe velocity is just 0.1 bar compared with 0.5 bar for a conventional valve. This is especially important when used on non-boosted systems since mains water pressures are being lowered down to 1.0 bar (@ 9 lt/min) in many regions. Flat-faced union connectors with soft washers allow valves to be easily installed to new or existing pipes without the need to spring pipes apart. This system allows for numerous pipe systems – see below. Valves are demountable. Sprung-loaded Cartridges with resilient seats provide positive closure, no water hammer and low opening pressure.
