The BWT D1 pressure reducer protects water supply systems in single and multi-family houses, commercial and industrial buildings from excessive supply
pressure in accordance with ÖNORM EN 806-2 in conjunction with DIN 1988-200. It thus helps to avoid pressure damage, reduce water consumption and
ensure sound insulation. The D1 is used to reduce the pressure and regulate the desired downstream pressure and keep this constant, even if the upstream
pressure fluctuates significantly. A constant and not too high pressure protects fittings and devices in the entire water supply system.
