how to change safety valve of pressure cooker brands

Pressure cooking is a wonderful way to prepare food that cooks thoroughly and quickly at a high temperature. Some are worried about the dangers of using a pressure cooker, so it is helpful to find out how to check your pressure cooker safety valve for safe operation.

For those worried that a pressure cooker might explode, the safety valve is the design feature that prevents this from happening. If the cooker has a safety valve, you can see it installed on the cooker’s lid.

A pressure cooker is designed to trap the steam inside to increase the pressure. However, too much pressure is not safe. The valve must release pressure if it gets too high.

The blog of pressure cooking today has many recipes that are delicious. There are 25 recipes for pasta so you can try a new one every day for nearly a month.

There is a weight inside many of the safety valves that is lifted by the internal steam pressure when it reaches a certain amount. When the pressure lifts the weight inside the valve, this allows some steam to escape.

Jeffrey Eisner who says “he is a nice Jewish boy from Long Island.” He started with pressure cooking by making a simple mac and cheese dish with a recipe that he shared on YouTube. The video was an immediate success and led to his making new recipes for pressure cooking.

In a sealed cooker, as the pressure builds up, the boiling point of water rises. This phenomenon is the cause of the increased heat that cooks the food more thoroughly and faster.

The science that explains this is fascinating. The normal boiling point of water under standard atmospheric pressure of 15 pounds per square inch (psi) is 212°F (100°C). In a pressure cooker, the atmospheric pressure doubles from 15 psi to 30 psi. This added pressure raises the boiling point of water from 212°F (100°C) to 250°F (121°C).

If you see steam escaping from the safely valve do not worry. The steam escaping from the safety valve is its normal function, which means the valve is working properly.

If the internal pressure within the cooker gets high enough, this lifts a weight in the safety valve that allows steam to escape. The escaping vapor lowers the pressure. You can hear the steam escaping, making a whistling sound, or rattling the valve.

The first pressure cooking devices were used in the 17th century. They were useful to remove fat and collagen from bones so that the bones could then be ground down to make a pure bone meal.

The inventor of the device, Denis Papin, called it a “steam digester” or “bone digester.” His invention was the precursor to both pressure cookers and the steam engine. Surprisingly, the early designs did not have any safety features, and this caused some of the first ones to explode while being used.

The legacy of those early pressure-cooking devices may be why some still fear this problem even today. Papin, to his credit, came up with a design improvement that is what we call a safety valve to avoid the dangers of these explosions.

By the 1930s, the modern pressure cooker design became useful in a home kitchen. The Flex-Seal Speed Cooker, invented by Alfred Vischer, came out in 1938.

These home cookers became even more popular in 1939 with the release of the design by the National Pressure Cooker Company (now called National Presto Industries), which is still manufacturing these cookers today.

The first-generation cookers had a safety valve that worked with a weight. When the internal pressure rises high enough to lift the weight, some steam escapes, and the valve makes a distinctive rattling sound.

Second-generation cookers use a spring-loaded valve that makes less noise and is adjustable for pressure sensitivity by using a dial, which is on the cooker.

Third-generation models are the most recent versions. They use an electric heating source that is regulated by the internal pressure. These devices do not need a safety valve because the heat source automatically shuts off before the pressure gets too high.

Suppose you are thinking about getting a new cooker. In that case, there is another device that you might consider called a food dehydrator, which I describe in the article entitled, “How Much Electricity Does a Dehydrator Use?” here.

For the styles of cookers with a safety valve, it may not be obvious when the valve is not working if it is blocked. You may notice the lack of steam while the cooker is heated. The valve could rarely be blocked, but if not cleaned properly, it is possible.

Alternatively, the valve may be broken, missing, or the pot may not seal properly. These problems might allow too much steam to escape. This leakage may cause the cooker not to heat up properly and not allow the internal pressure to build up to the proper level.

One of the signs of a problem with a lack of pressure is that the food takes much longer to cook than you normally expect when using a cooker of this type.

One tip in the video is not to open the cooker after finishing cooking and take the lid to run it under cold water. This sudden temperature change can make the safety valve work less well and may cause the need to change the valve more frequently.

If you use a cooker that needs a valve to work properly and the valve is broken or missing, you can replace it with a new valve. Be sure to get the manufacturer’s specifications to ensure you use the correct replacement part.

Some of these problems include the ventilation knob being open or not enough liquid is in the cooker (requires at least one cup). Another cause is the sealing ring is missing, damaged, covered with food particles, or not in the proper position.

The video narrator shows how she cleans her float valve for her instant pot that she uses as a cooker. If you use too little liquid or too much, the cooker may not pressurize.

For the type with screws, hold the valve from the bottom of the lid with the pliers and use the screwdriver to remove the screws from the top to remove the broken part. Replace it with the new one and tighten the screws that hold it in place by holding it with the pliers from the bottom of the lid again and tightening the screws from the top.

For the type with a nut, use the wrench to loosen it for removal and perhaps a socket when you put on the new valve to tighten it with enough torque to hold it securely in the proper position.

Modern pressure cookers that are in good repair are quite safe. The one caution to remember is not to overfill the cooker so that the food might block the safety valve. This overfilling with food would be very difficult to do and not something to worry about for normal use.

Be careful where you keep your cooker on the countertop because it is important to know how hot a stovetop can get. Even when turned off, a stovetop may still be very hot, which I discuss in this article.

Now you know everything you need to know about a pressure cooker safety valve. You know what they do, how they work, and how to replace one if it needs repair. Enjoy your pressure-cooking recipes without worrying about the safety valve.

If having a safety valve on your cooker still bothers you, consider buying an electric cooker without a valve that instead has a built-in safety feature that automatically shuts off power if the pressure gets too high.

Pressure cookers have become an essential part of everyday cooking. As they don’t have any complicated functionalities, they are quite easy to prepare.

However, in technological aspects, a pressure cooker is a bit complicated. In order ensure user-safety, they have been equipped with different safety features – among them safety valve is a crucial one.

Pressure cookers have to deal with a lot of steam pressure in the cooking process. At some point, it has to release the excess steam to prevent the cooker from blowing up or exploding.

This release happens through the safety valve that holds weight. When the pressure is too high, it lifts the weight and steam escapes through making a buzz sound.

One of them is a classic whistle with pressure regulating valve and another is pressure regular valve present a little away from the first one. It is fixed onto the cooker lid and made from synthetic rubber like hardened viton or neoprene which helps in maintaining the pressure and good seal.

When the pressure inside the cooker increases, the inner part of safety valve will sense the elevation. And when it exceeds the normal levels, the rubber will start to melt and disc will lift.

Once the excess pressure is released, the disk goes back into its position. And the safety valve will open only when other means of steam release have failed as a last resort to prevent any explosion.

Pressure or steam release doesn’t always mean danger. It mostly indicates some dysfunctions that need attention. We have mentioned some of the possibilities below for your reference.

Damaged gasket – Usually, a rubber ring is present to seal the cooker. When there is a damage to it or if placed unevenly, it can compromise the cooker seal and let the pressure escape through the safety valve.

Overfilled pressure cooker – If the appliance is filled up with food ingredients without any space left for the steam, then this can block the regulating valve due to food expansion or foaming.

If the pressure cooker is made from cheap quality and from on an unknown brand, then they are a safety hazard as they compromise on the protection and health of a consumer. They often have low-quality safety valve which malfunctions easily and lead the steam to escape.

When the food and water quantity is little and water boils away, this can result in burnt and empty cooker. And the temperature gets too hot very quickly, leading to break down of the safety valve.

If the pressure cooker is placed over a larger burner and on a high flame, then the flame starts licking the sides of the appliances, leading to high temperature build up and damaging the safety valve.

Not cleaning the pressure cooker regularly can lead to clogs in the pressure regulating valve and this lets the safety valve to emit the steam from the cooker.

Some of the models come with a manual setting sealing feature. In such case, never forget to turn them on or else the steam takes safety valve for escape.

If you suspect the pressure cooker is not because of the safety valve, then the first thing is to take the appliance to the nearest service centre. You can use the cooker without the lid on but it is better to avoid using it with the lid until you get it repaired.

Yes, it is possible to replace safety valve of a pressure cooker. And moreover, it is recommended to replace it if the valve is out of friction or damaged.

Replacing the safety valve can be done in two methods – one includes changing it from inside and another from the outside. Below are the clear instructions for the same.

Replacing from the outside – You have to insert a blunt knife and turn the screw into the hole from outside. Make sure to hold the screw on the inside while doing it. Turn the knife by turning the screw which loosens it up eventually.

Make sure the pressure cooker is filled up to only 2/3 full and the rest of 1/3 part has to be empty so that the foods have enough space to swell and foam.

It is important to add adequate amount of liquid into the pressure pot. If not, the water runs out quickly, cause rapid heat increase and lead to explosion. Not to say that burns caused food burns as well.

To maintain the pressure cooker longevity and prevent any disasters, it is important to check the safety valve and gasket on a regular basis. If there is any damage, getting it repaired or replacing is very important. Safety valve in a pressure cooker plays a very significant role.

The safety valve inside a pressure cooker is a safety backup mechanism that comes into effect when the pressure inside the cooker turns uncontrollably high and finds no path to escape.

To release steam, the cooker has pressure regulating valves that Jiggle or extend outwards with the help of spring. Some release steam with the help of a computer chip!

If for any reason, the pressure regulating valve fails to release steam, the excessive pressure causes the safety valve to open up and release steam in a controlled way.

The other valve is located a little away from the pressure regulating valve. It is screwed on the lid of the cooker and is made up of synthetic rubbers like neoprene or hardened Viton.

If you see pressure steam coming out of the safety valve, it does not signify danger. It only points to some possible dysfunctions that need to be taken care of.

Damaged Gasket. A gasket is a rubber ring that helps to seal the cooker. A damaged or uneven placement of the gasket could lead compromise the seal of the cooker leading to pressure escaping from the safety valve.

Cheap quality pressure cookers made from an unknown brand are a safety hazard as they compromise on health and protection of the consumer. Low-quality safety valves malfunction easily causing steam to escape.

If the quantity of food and water is too less and water boils away, it can result in a burnt and empty cooker. Since the temperature and time duration is not controlled, the temperature inside the cooker becomes excessively high quickly leading to the safety valve breaking down.

If the pressure cooker is placed on a large flame, the flame starts licking the side walls leading to excessive temperature building and safety valve destruction

If the pressure cooker is not regularly cleaned and maintained, it can clog the pressure regulating valve forcing the safety valve to emit steam out of the cooker.

Some models come with a sealing feature that needs to be set manually. Forgetting to turn them on can cause the steam to escape from the safety valve.

For traditional pressure cookers, failure to manually adjust the temperature and pressure causes excessive pressure build-ups causing the safety valve to break or melt.

You can replace the safety valve from the outside by holding firmly the inside part so it doesn’t move. Use a screwdriver to rotate and twist the screw on the outside until it comes off.

Always buy from trusted brands as they ensure quality checks when it comes to material and usage. No amount of budgeting should compromise your safety and good health.

Make sure the rubber rings and the lid of the cooker are closed properly and in correct alignment. If the rubber ring has become loose, it is best to replace it.

Follow the tips above to avoid steam coming out from your safety valve. If, despite all precautions, the safety valve opens up, replace it with a new one.
