High Pressure Expansion Control Valves

High Pressure Expansion Control Valve

The RMC High Pressure Expansion Control Valve limits the maximum pressure in a pressurised, unvented water heater system by relieving excess pressure to the drain line.

  • Increased heating efficiency
  • Releasing pressure at the inlet saves energy by not purging heated water
  • Auxiliary pressure relief device
  • Additional protection in the event of drain line blockage obstruction
  • Dezincification resistant
  • Meets Australian Standard for potable water supply
  • Sealed spring cavity prevents spring from seizing in the event of calcification
  • Valve designed to work effectively in vertical or horizontal installations
