The Duromatic Pressure Cooker - Full Steam Ahead Since 1949
Following the acquisition of their original premises in Rikon (near Zurich), Switzerland in 1926, Kuhn Rikon’s ever-present association with pressure cookers was initially stimulated by the need for cookware that was compatible with the then brand new electric stoves. One year later - and under the ‘Duro’ trademark - the company’s first successful cookware was manufactured.
The Duromatic Pressure Cooker was developed in 1949 and quickly became synonymous with all pressure cookers. An instant hit, the hugely successful product became Kuhn Rikon Switzerland’s very first export.
The Spring-Loaded Valve - the Key to a New Generation of Pressure Cookers
Although popular at that time, preparing meals using an old-fashioned weight-valve pressure cooker was accompanied by an element of fear, predominantly due to the constant sound of hissing that they routinely produced.
That all changed when Jacques Kuhn, an engineer and future manager of Kuhn Rikon, developed the spring-loaded valve that is now integral to all new-generation pressure cookers.
As well as eliminating disconcerting noise, the revolutionary new valve prevented the substantial guesswork that had traditionally been associated with pressure cookers. Instead, a new degree of precision timing was now possible and the risk of over-cooking food was dramatically reduced.
Steam Pressure Inside a Duromatic - a ‘Red Ring’ of Precision
The ingenious spring-loaded valve of Duromatic Pressure Cookers contains two red rings within its stem. The rings accurately reflect the internal pressure within the pan at any time. The first red ring denotes a pressure of 5.8 PSI (pounds per square inch). The second red ring signifies a pressure of 11.6 PSI. The stem of the valve automatically rises as the pressure increases and the heat from the stovetop should be modified accordingly in order to maintain the correct pressure. A PSI of 5.8 is associated with a temperature of 229 degrees Fahrenheit/109.44 degrees Celsius. A PSI of 11.6 corresponds to a temperature of 243 degrees Fahrenheit/117.22 degrees Celsius.
The cooking times for many foods/meals are associated with specific PSI levels.
Too Much Pressure - not With Duromatic!
Duromatic Pressure Cookers incorporate multiple steam release safety systems that prevent the attainment of excessive/potentially dangerous pressure levels. Once the spring-loaded valve rises beyond the second red ring, pressure is automatically released. Steam is also able to escape from multiple locations when necessary. If the main valve becomes clogged or damaged, an alternative valve and safety path is activated.
In addition, Duromatic Pressure Cookers feature an automatic lid locking system. It is not possible to remove the lid when any pressure exists within the pan. The pressure must be released in its entirety before the lid can be detached. This is accomplished by either manually pressing the spring-loaded valve or via a natural cooling process once away from the heat source.
Premium-Quality Materials and Cutting-Edge Manufacturing Processes
Kuhn Rikon Switzerland only selects the finest raw materials for their cookware. The 18/10 stainless steel from which the Duromatic Pressure Cookers are crafted is rust, corrosion and chip resistant. Unlike cheaper alternatives, the quality of the stainless steel is reflected by its substantial weight and robustness.
Kuhn Rikon Pressure Cookers are not allowed to leave the factory until they are subjected to a rigorous durability test that replicates 50 years of use.
The state-of-the-art production processes are planned and regulated by computers. This includes the bending of the sheet steel and fusing it onto the multi-layered base plates. All joints are then checked using electronic monitoring equipment.
Many of these procedures were developed internally as a result of Kuhn Rikon Switzerland’s significant knowledge advantage in relation to the manufacturing of high-class pressure cookers.
The Superthermic Sandwich Base - Save Time and Energy
The ability of Duromatic Pressure Cookers to prepare food so efficiently (using 70% less energy/taking one third of the time) is largely attributable to their sophisticated aluminium Superthermic sandwich base. Its waved/corrugated profile not only provides high stability and resistance to distortion, it also ensures optimal and uniform heat distribution. When exposed to heat the material expands so that even the middle of the base is in direct contact with the hob/stovetop, something that isn’t achievable with standard cookware.
The Inox Range - Elegant and Timeless
Kuhn Rikon offers a wide variety of pressure cookers within their famed Duromatic assortment. The Inox model features a distinctive domed lid and boasts an elegant design that has remained popular for decades.
It is available in numerous different sizes and with either side-grips or a long handle.
Use and Care Instructions
Duromatic Pressure Cookers are designed to provide a lifetime of regular usage. Following the below guidelines will help to ensure that their longevity is maximised.
1) Although the pot is dishwasher safe, cleaning by hand is less abrasive and is therefore recommended.
2) Warm water and conventional detergents are sufficient for normal soiling.
3) For more intensive soiling or scale, use a chromium steal cleaner.
4) Remove any limescale effectively using vinegar or lemon juice.
5) Avoid the use of knives, steel wool or metal scourers when removing stubborn food (they will scratch).
The 10-Year Guarantee
Duromatic Pressure Cookers are guaranteed for a period of 10 years from the date of purchase in accordance with general domestic usage. The spare parts (valve, gasket etc) are guaranteed for a period of 1 year. They can be purchased separately as extras/replacements if necessary.

This literally changed the way we eat, going from never cooking a dried bean in my life to doing batches at least 3 times a week.
The best tip i ever had was to start with boiling water, this takes the time to get up to pressure from 10mins down to 2-3, so I can cooked soaked beans in 15mins tops from start to finish.
There are very few things to criticize as its so easy to clean and maintain and quick releasing the pressure is safe and easy. Occasionally we would have to pull up the weight as it got stuck, and if the seal inst quite right steam can escape form the handle.
If you want a manual pressure cooker, this will certainly last for many many years and spare parts are readily available. The manufacturer prides itself on having spare parts available well after they stop producing models.
I can't rate this highly enough but here is the big but...We originally purchased this over an electric pressure cooker because of its longevity, we didn't want an electrical appliance that would break down after a year. Having had this for a yeah though i'd given up making big batches of chilli etc because it tended to spit and block up the seals. On a gas hob it also requires supervision to tweak the flame to maintain a steady pressure meaning you can't just walk away form it for more than a few minutes or it will either be over or under pressure.
I took the risk and purchased the instant pot, and in all honesty the manual cooker hasn't been used since. The electric cookers are slower as they work at a lower pressure, its perhaps 15% slower so not as good if you want to make a quick dinner but the enourmous benefit is that you can just walk away from it. This means you can re-create slow cooked dishes and cook beans direct from dry and not have to be even in the house for the 25mins to an hour it takes. I now cook 4-5 dishes a week in the instant pot cooking anything from beans,potatoes,soups and stews to steamed veggies and baked potatoes.
So really you need to weight up if you want quality that will last a lifetime, or convenience and versatility. Both are high ticket items and I don't regret either purchase.
I had exactly the same problem. I called the company (in the UK) and they spotted the problem straight away. Actually NOTHING WAS WRONG WITH THE COOKER, I just had to lift the black valve cap to the level of the 2 red lines with one hand, with the other hand, I had to screw the valve properly (it was only unscrewed). I want to make it right as I found unfair that the Kuhn Rikon Company got a negative feedback because the top valve was just unscrewed. I HIGHLY RECOMMEND this pressure cooker and thanks for Kuhn Rikon Company who solved this problem very quickly.
The pot heats up super quickly and it's very easy to clean; the heavy bottom and thick walls keep temperature very well, and as a result, I've used the pot for pretty much anything — from sautéing to deep frying. Obviously I bought it because I wanted a pressure cooker — and that's where it really shines.
The valve at the top has 2 indicators for the pressure level. As the pressure increases, the valve slowly starts coming out. From what I can see, this pressure cooker achieves higher pressure than other brands (e.g. Tower) so it cooks food much quicker. The cone metal part diffuses any steam that might come out. The material is quality stainless steel, so you can use Bar Keepers Friend to keep it looking brand new.
As a bonus, the item comes with a booklet with cooking times for all kinds of food — from meat and legumes to fruits.
Overall, it's a fantastic pressure cooker, but clearly it comes with a price tag to match.
I bought this 6ltr 24cm pressure cooker specifically for steaming Christmas pudding which i did the day after taking delivery. it's brilliant and sat quietly on the hop clinking away with the metal pud vessel inside sitting on top of the stainless steel trivet which comes with it and is essential for keeping it of the pot bottom. minimum heat required but i think i will buy a defuser only to spread the heat even more and to protect the pot. It lost about half a litre of water over the 2.5 hours it was steaming away as i couldn't reduce the heat any more on the smallest gas ring. so not only do you not get a greasy steamed kitchen but it takes a 1/3 of the time and minimal gas. What more could you want.
