BWT D1 pressure reducer - champion of all classes
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, thus helping to prevent pressure damage, reduce water consumption and ensure sound insulation. The D1 is used to reduce pressure and regulate a desired back pressure and keeps it constant, even if the upstream pressure fluctuates greatly. An even and not too high pressure protects fittings and equipment in the entire water supply system.
