Resideo DRG Three-Way Mixing Valve

The Resideo DR300 Pressure Reducing Valve is designed to safeguard downstream installations from excessive supply pressure. Pressure regulators are essential when the capacity of directly controlled pressure reducing valves is inadequate. Their compact design makes them particularly suitable for installation in confined spaces, such as ducts. By incorporating a pressure regulator, you can prevent pressurisation damage and reduce water consumption. The set pressure remains constant, even amidst significant fluctuations in inlet pressure. Additionally, reducing the operating pressure while maintaining a consistent level minimises flow noise within the system.

The PREL101016 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system at a predetermined pressure in the event of over-pressurisation. This robust valve is an essential safety feature, primarily utilised in sealed heating systems. Upon installation, the pressure relief valve is calibrated to the appropriate pressure setting. If the pressure within the system increases beyond this threshold, the valve activates, allowing excess pressure to be released into the atmosphere. This action safeguards the system from reaching hazardous pressure levels that could potentially cause damage or pose risks to individuals nearby.

Features and Benefits:

• Diaphragm design enhances resistance to scaling, significantly extending its lifespan.
• The single-piece cartridge allows for straightforward removal, facilitating easy access for cleaning or replacement.
• The adaptable relief pressure range of 2.0 bar to 6.0 bar offers flexibility for various system designs.
• Available with FSBP or MBSP/FBSP connections, providing complete installation versatility.
• Specifically designed for heating applications.
