The BWT D1 pressure reducer protects water supply systems in single and multi-family homes, 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 prevent pressure damage, reduce water consumption and ensure sound insulation. The D1 is used for pressure reduction and adjustment of a desired back pressure and keeps it constant, even if the inlet pressure varies greatly.A uniform and not too high pressure protects fittings and equipment in the entire water supply system.
