Pressure and Temperature Relief Valves

Pressure and Temperature Relief Valves

RMC’s Pressure and Temperature (P&T) Relief Valves are safety controls for unvented water heaters. They ensure that the pressure and temperature of the water do not exceed 99°C in the event the normal thermostatic controls fail.

  • Auxiliary pressure relief device
  • Prevents pressure building up in the event of a blockage in the drain line
  • Female BSP thread on outlet thread prevents incorrect installation to the tank
  • Plastic coated temperature probe prevents electrolysis of the probe outer casing
  • Dezincification resistant
  • Meets Australian Standard for potable water supply
  • Sealed spring cavity prevents spring from seizing in the event of calcification
  • Suitable for horizontal or vertical installation
  • Individually tested and calibrated
  • Every valve is tested to ensure high quality and performance
