What it is

The Altecnic temperature and pressure relief valve (TPRV) is a safety valve used on boiler systems within the Altecnic TPRVs range. It opens at 7 bar or 90°C to relieve excess system pressure or temperature through a 3/4 x 22mm connection. A 99mm probe acts as the temperature-sensing element.

Signs this part needs replacing

  • Continuous drip or weep from the discharge outlet when the system is at normal pressure
  • The valve fails to open during a pressure or temperature test
  • Visible scale, corrosion or debris on the valve seat, body or probe
  • Water discharging at temperatures or pressures below the 7 bar / 90°C settings
  • Damage or leakage at the valve body, probe or connection

Before you order

  • Confirm the system requires a 7 bar / 90°C TPRV, checking the boiler data plate
  • Check the existing valve connection matches 3/4 x 22mm
  • Measure the probe length needed; this valve has a 99mm probe
  • Confirm compatibility with the Altecnic TPRVs range
