Temperature and pressure relief valve JD-AQF0023 Description
The valve opens the outlet on reaching the settings for:
- temperature: the thermostat compound inside the temperature sensor 1) submerged in the hot
water storage heater, expands as the temperature increases. This expansion causes a thrust
pin to move and act on the obturator 2) opening the valve. The valve is set to open at
temperatures of over 90°C.
- pressure: the obturator, opposed by a set spring, raises on reaching the pressure setting and
opens the outlet completely. The pressure setting is chosen according to the maximum
permissible pressure in the system.
As the temperature and pressure decrease, the opposite action occurs with the valve
subsequently reclosing within the set tolerances.
