Once the water inside the pressure cooker boils, it creates pressure which pushes the valve up, and creates a sound. Once the pressure has come out and has reduces, it is not able to push up the valve anymore. The valve also acts as a regulator of the pressure, so that it may not exceed and lead to over pressurizing. This will keep to a temperature of 121C.

+ Ring

This is a rubber ring that is found round the lid. It is used to help tighten the lid together with the pot. This will prevent the pressure from escaping between the lid and the pot. It is important to ensure that you have cleaned the ring well, and positioned it well so that it closes well.
