Product Description

RMC's High Pressure Expansion Non-Return (HPNR) Valves are suitable for coil type heat exchange water heaters. The valve is a combination non-return and pressure relief device. The non-return prevents the backflow of hot water into the mains supply. The
relief valve prevents an over-pressure condition within the coil.

High Pressure Expansion Non-Return Valves limit the maximum pressure in a system by relieving excess pressure to the drain line and are classified as a functional control for this type of application.
HPNR Valves should only be installed on the cold or inlet installation on a water heater as the valve is primarily intended to cope with the excess pressure generated during a normal heating cycle.

RMC's HPNR Valve is available in a 15 mm configuration.

  • Economical one-piece construction
  • Increased heating efficiency
  • Suitable for horizontal or vertical installation
  • Dezincification resistant
  • Meets Australian Standard for potable water supply
