Reliance RWC 101 Series Pressure Relief Valve 3/4" x 3/4" F x F 3 Bar - PREL101013

The Resideo Braukmann D15S is a highly regarded pressure reducing valve (PRV) commonly used across the UK and Europe for drinking water applications. This essential device serves to safeguard domestic water systems from excessive supply pressure, ensuring optimum performance and longevity. It is also suitable for industrial and commercial applications within its specified range. By installing a pressure reducing valve, you can effectively prevent damage caused by high pressure and reduce overall water consumption. The D15S maintains a consistent set pressure, even amid significant fluctuations in inlet pressure. Furthermore, by regulating the operating pressure, this valve minimises flow noise within the system, enhancing comfort and efficiency.
