How do you replace safety valve on Lagostina pressure cooker?

Answer 1

Yes, it has one. It's on the top of the lid. On the exterior surface.

Unless you put the pot on high heat and leave it there it won't be necessary for you to even think about it.

Heat the pot on as high a heat as the food inside will tolerate without scorching or burning. With soups it can be on high heat, with tomato dishes or other more likely to burn foods, start on medium heat.

When you hear the pot hissing and see the little locking pin rise, reduce the heat as low as you can.

You need only to maintain the pressure, so you don't need the stove on high. If you leave it on high all you're doing is wasting heat, burning food and perhaps blowing the little pressure ring.

I've used mine for a decade and never had to replace the pressure ring.

I highly recommend the Lagostina because there is no large, internal rubber gasket which may not always seal properly, will eventually crack and lose flexibility and will need to be replaced.

A quality product that will save hours in the kitchen and cut your energy bills way down if you use it properly. Well worth the $$$$.

I hope this answers your somewhat ambiguous question and that you'll take a look at the product's manual which is online.
