The T&P relief valves provide fully automatic pressure and temperature relief protection for heaters and hot water storage tanks. The thermal probe is the key component of T&P valve, when sensing excess pressure or temperature, the probe expands and lifting the valve’s disc off its seat to discharge overheated water.
Wisdom probes start motion at right 93°C, increase stroke as temperature rises, perfectly cover the valid working temperature range of T&P valve.
Once the working temperature reaches, the valve opens and discharges pressure and water as rapid as possible, to improve safety and reliability.
