DN25 316 Double Check Valve Stainless Flat-Face

Double Check Valves with 316 stainless steel valve bodies suitable for all pipe materials - no risk of galvanic corrosion. 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 DCV at 3 m/s pipe velocity is just 0.1 bar compared with 0.5 bar for conventional valves. 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. Valves are demountable. Sprung-loaded Cartridges with resilient seats provide positive closure, no water hammer and low opening pressure.
