PREssuRE REDuciNg VAlVE • EN-DRV 4 - High corrosion resistance: The corrosion resistance in particular is guaranteed for all used materials. The housing is made of dezincification resistant brass (DZR). - Unique filtering system: The high capacity inspectable filter cartridge can be unscrewed without using special tools (which is not the case of others solutions available on the market). Unlike other pressure reducing valves, the transparent bowl is NOT the container of debris. Debris are blocked into a special transparent 3 legs storage. This operational principle provides many advantages : ➪ when a draw-off outlet is opened on the water system, the debris are NOT into the flow, this does not affect the quality of the water, ➪ the flow capacity is not reduced or disturbed by the amount of debris as they are stocked into a storage, ➪ the low pressure losses of EN-DRV series are guaranteed whatever the level of clogging. The transparent filter cartridge (storage and bowl) can be visually checked and easily removed for cleaning and maintenance work. specifications: • Connections sizes: Unions threaded 1/2”, 3/4”, 1”, 1”1/4, 1”1/2, 2”, and Comp. fitting 15mm, 22mm. • Pressure setting range downstream: EN-DRV, EN-DRV/R, EN-DRV/F: 1 to 6 bar (1 to 5,5 bar for NF approved model). • Pressure gauge connection: two 1/4” F are located on each side of the valve. • Max. upstream pressure: 25 bar, (EN-DRV/F: 16 bar). • Max. working temperature: - EN-DRV, EN-DRV/R: 70°C - EN-DRV/F: 40°C.
