Caleffi TPR Valve 20mm 700kPa

Caleffi temperature and pressure relief valve
20mm, 7bar, 90°C

The TP relief valve controls and limits the temperature and pressure of the hot water contained in a domestic storage heater and prevents it from being able to reach temperatures of over 100°C, with the formation of steam.
On reaching the settings, the valve discharges a sufficient amount of water into the atmosphere so that the temperature and pressure return within the systems operating limits.
