Product Details

The BWT D1 pres­sure reducer protects the water supply system ans appli­ances in single and multi-​family houses, commer­cial and indus­trial build­ings from the poten­tially damaging effects of exces­sive mains water supply pres­sure in accor­dance with ÖNORM EN 806–2 in conjunc­tion with DIN 1988–200. I t helps to avoid pres­sure damage, reduce water consump­tion and ensure sound insu­la­tion through reduced vibra­tion and 'knocking'. The D1 is used to reduce the pres­sure and regu­late the desired down­stream pres­sure and keep it 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.

FAQ

What is a pres­sure reducer needed for?

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.

What prob­lems can arise from pres­sure fluc­tu­a­tions or without a pres­sure reducer in water pipes?

  • Water leaks from poor joints and damaged pipes
  • In extreme cases even burst water pipes
  • Noise nuisance due to pres­sure peaks that can cause vibra­tion and 'knocking'
  • Increased water consump­tion and costs

Does a pres­sure reducer have to be serviced?

ÖNORM EN 806-5 recom­mends that a pres­sure reducer be inspected or serviced annu­ally.

Master­piece

D1 - The new BWT pres­sure reducer impresses with its construc­tion, the choice of mate­rials, and its very easy oper­a­tion and last but not least, the opti­miza­tion of pres­sure and flow behavior: expressed in a number - Kvs value* 9.3m³/h (DN 25).

  • Patented Venturi effect delivers the highest flow rate with perfect pres­sure control
  • Up to 50% heavier than compa­rable prod­ucts (e.g. weight D1 Red 1 “: 1.7 kg vs. competitor 1.14–1.4 kg)
  • Up to 16 or 25 bar inlet pres­sure

*The Kvs value expresses the flow rate in a pres­sure regu­lating valve when the valve is fully open and a pres­sure differ­en­tial of 1 bar.
