Are pressure cookers dangerous?
The DUROMATIC pressure cookers belong to the new generation of pressure cookers. They are built with safety features that make it impossible for a disaster to occur.
First, the automatic lid-locking device of the DUROMATIC pressure cookers ensures that no pressure can build up until the lid is put on correctly. The lid cannot be removed or come off until all of the pressure has been released.
DUROMATIC pressure cookers provide the ultimate protection against excess pressure. The first indication that too much pressure has built up inside the cooker is the audible hiss of the valve as excess pressure is released through the valve. When the user hears this, the heat should be turned down. As long as the valve is not clogged, it will take care of any over pressurisation by allowing steam to escape through the radial escape holes located on the valve stem.
Other safety releases will come into effect only if the central valve is clogged. If that occurs excess pressure will also escape through the safety holes in the rim of the lid.
Additionally, another spring-loaded safety valve in the lid is set to release steam in case of a clogged main valve due to overfilling or too-high heat. This valve is not a "blow plug" like some old American cookers had, but a highly accurate spring-loaded valve which will open at a pre-set internal pressure and release steam safely and effectively.
Finally, at higher pressure, the gasket is forced out through the six bayonet flanges in the lid, and a jet of excess steam escapes (once again in a downward direction.)
