Reliance RWC 101 Series Pressure Relief Valve 1/2

Reliance RWC 101 Series Pressure Relief Valve 1/2" x 1/2" M x F 6 Bar - PREL101010

Introducing the PREL101010 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve, an essential component designed to discharge water from your heating system at a predetermined pressure in the event of over-pressurisation. The Reliance Valves 101 Series Pressure Relief Valve serves as a vital safety feature in sealed heating systems, ensuring optimal performance and risk mitigation. Upon installation, this reliable valve is calibrated to the correct pressure; when the system pressure increases and reaches the preset limit, the valve automatically opens to release excess pressure into the atmosphere. This crucial mechanism helps prevent the risk of excessive pressure that could potentially harm the system and pose a hazard to individuals nearby.

Features and Benefits:

  • Innovative diaphragm design enhances resistance to scaling, ultimately prolonging the lifespan of the valve.
  • The easy removal of the single-piece cartridge allows straightforward access to the seat for cleaning or cartridge replacement.
  • Flexible set relief pressure range from 2.0 bar to 6.0 bar accommodates various system design requirements.
  • Available with FSBP or MBSP/FBSP connections, offering complete installation versatility.
  • Designed specifically for heating applications only, ensuring optimal functionality.

Specifications:

  • Size: 1/2" x 1/2"
  • Connections: BSP Male Inlet x BSP Female Outlet
  • Materials: Hot pressed DZR Brass
  • Medium: Water
  • Set Pressure: 6 Barg
  • Temperature Rating: +140°C
