bialetti moka express safety valve replacement manufacturer

The devil is in the details. It is often the smallest things, the particularities, that make all the difference. This is also the case in regards to the preparation of a good coffee, a ritual in which all the steps and every single component play a fundamental role. Among all, one of the most important elements is the Moka valve. Often ignored, it is vital not only for the quality of the coffee, but also for the safety of those who prepare it.

The valve was born with the invention of the Moka Express in 1933. It is a safety valve positioned on the bottom chamber. To better understand the importance of the valve and its use, we need to take a step back and illustrate step by step

This is where the valve of the Moka comes into play. It must open when the pressure is too high. By doing so, it allows the steam to escape regularly, without causing any damage. In short, the Moka’s safety valve provides security. Hence, it should only intervene when the coffee maker is used under abnormal operating conditions.

A long-standing and debated question: how far can you fill the bottom chamber for a state-of-the-art coffee? The Moka valve can come in handy to answer this dilemma. Another important role of the valve is that it acts as a "measuring cup". Its position on the bottom chamber is not accidental. Rather, it indicates to those who prepare the coffee the correct amount of water to use. The only exception is for some special coffee pots that are already equipped with a measuring cup. Ideally the water should reach just below the safety valve.

The Moka valve, therefore, is not a decoration or a mere design element. Rather, it is a very important component for the correct functioning of the coffee maker. It guarantees safety and plays a part in the making of an excellent coffee.

Consequently, it is necessary to keep it clean and maintain it regularly. For example, using tap water to make coffee brings with it the risk of limescale deposits obstructing the hole in the valve. The resulting danger is that it could get clogged.

We have seen that one can simply use hot water to clean the Moka valve. To avoid limescale obstructions, simply move the piston that comes out of the valve along its axis when washing it. To ensure the Moka functions correctly, it is recommended to repeat this checkup periodically.

PART NUMBERS & MANUFACTURERS REFERENCE: Many of the parts on sale are supplied by the original equipment manufacturers (OEM) whilst others are offered as suitable replacements or alternatives. Any references made to specific manufacturers and OEM part numbers are for guidance and identification purposes only and does not imply that any parts supplied are purchased direct from the OEM. Parts supplied as alternatives may differ from the OEM"s exact specifications.

Works as expected. Speculate that seller source is not the OEM but is assembling stock that failed spec with the OEM who then sold it at a pittance to the seller source. Reasonable considering that the molded polymer neck exhibits crazing and stress factors indicating issues during the molding process. The supplied O - Ring to replace the stem seal is a red non silicon rubber type normally associated with plumbing (the original is most certainly clear silicon rubber). It took a few twists back and forth and downward pressure to work in the seat so that it engaged correctly. Lastly, as a caution I ran a narrow dia. Wire through the froth orifice to clear any residual flash or obstruction that might be lurking (in fact I was alert to this from reviews-as well as visual confirmation of a very weak flow of water through the port as a test). The wire cleared the port as water now flowed out just like my old one did so I prepped the unit to commence cappuccino making. Result. Rewarded with exactly what I expected; hot frothy cappuccino. Seller correspondence was great and part came like three weeks earlier than indicated so hats off to seller for excellent customer service. My advice as to product quality is to be prepared to inspect, be patient, and think through how to optimize the unit, and realize that yeah it may not be perfect. If you love your mukka express and you already popped for the gizmo to make it work again it"s worth solving minor issues. Oh, and don"t lose the little red o ring. It"s barely noticeable mounted to the cardboard with cut out tabs from the cardboard so the thing could fly if you tear the package open. On the other hand the local hardware store sells tons of tiny silicon o rings so that should be easy to replace-just bring the mukka in with you and let the hardware guy find the right one. Fun fact: the USA is and will always be the plastic injection molding world class leader. We are that damn good!

Been using my Vigano stovetop coffee pot on an electric stove for about 6 years. When I first got it I meticulously filled it to just below the safety valve yet was still scared to death of the thing blowing up if I left it too long on the hot ring. Immediately it began to glub and blub Id take it from the hot ring and stand back until it became quiescent.

That was then! I gradually discovered that as long as one does not too strenuously tamp the coffee in the basket (an unnecessary step in any case), filling the base to above the valve and leaving the pot on a low, low setting after it has "perked", is perfectly safe and gives me several cups of HOT coffee instead of one hot and the rest increasingly cooler.

Sorry, I wasn"t clear. I mean the pressure relief valve that is screwed into the side of the lower chamber. On all of my moka pots, this valve now leaks, so the pot never builds sufficient pressure to function.

I found a similar but slightly larger valve at MSC online, and was able to drill out and re-tap the hole in one of my aluminium moka pots to fit this valve with an o-ring. So that one is repaired. However, drilling out and retapping my stainless steel moka pots will be harder, and I am hoping to find the correct valve as used by Bialetti.

Edit: the valve I found is this one https://www.mscdirect.com/product/details/03244811 1/8" thread, 15-25 psi, $2.44. But it isn"t quite the correct thread to replace the original valve.

Exploding coffee makers—especially when they’re pressurized—tend to be day-ruiners. Yeah, cleaning isn’t that fun, but trust me…. it’s necessary, especially when it comes to moka pots. Safety and cleaning are actually interconnected with this brewer.

In this quick guide, I’ll show you how you can keep your moka pot in tip-top shapeandhow to stay safe so you never have to worry about a surprise kitchen explosion. Don’t worry—it’s all actually pretty simple.

Moka pots don’t just immerse coffee grounds in water. They create a ton of pressure that generates steam—and this pressure can be troublesome if your brewer’s not in good shape.

Now, moka pots do have asafety valvethat’s designed to keep too much pressure from building up in the device. Once more pressure than is necessary is generated, it starts to shoot out of the valve in the form of steam.

The valve is clogged with coffee grounds. If grounds happen to fall into the valve, they’re probably going to get stuck there. Over time, this can cause blockage in the valve and compromise its safety.

The valve is clogged with water gunk. If your local water source is ‘hard’ (has a high level of calcium and magnesium), you’re bound to see white gunk build up inside your moka pot over time. This gunk can be pretty stubborn and can clog the safety valve.

You tamped the grounds. Moka pots, unlike espresso machines, do not require you to tamp the grounds to get a balanced extraction. Tamping the grounds down into the filter basket can cause excess pressure to be generated. Just don’t tamp—you don’t need to.

You covered the safety valve with water. Over-adding water can cover the safety valve, which keeps it from being able to let out steam. Always leave a small amount of space between the water level and the safety valve.

Thankfully, cleaning your moka pot is a very simple process. It only takes a few minutes of your time, but it keeps your moka pot from destroying your kitchen—or worse—destroying your coffee’s flavor.

Over time, coffee oils and micro-grounds build up all over the insides of the moka pot. These are harmless when it comes to your health (unless those grounds are in the safety valve), but they do impact your brew’s flavor. Those old oils can go rancid and the grounds continually impart bitter flavors into later brews.

Once your moka pot cools, disassemble it and remove the filter basket. Toss the spent grounds into the garbage and thoroughly rinse and dry the filter basket. Now give the other pieces a good rinse and dry too. You can use a paper towel to wipe away and stubborn grounds from the basket or seal.

Don’t put the moka pot in the dishwasher. Don’t scrub the moka pot with an abrasive material. There’s a coating on aluminum moka pots that keeps your coffee from taking on a metallic taste, and you don’t want to accidentally scrub that off.

This basic process is really the key to a clean moka pot, but may not be enough if your water source is pretty hard. If it is, you’re going to want to give your moka pot a deeper clean twice a year or so if you use it regularly.

These two acids are strong enough to break down hardened calcium deposits but are generally considered safe for use with moka pots, both stainless steel and aluminum models. You can also use a dedicated coffee machine descaler, but chances are you already have these two acids available.

Add lots of water. Fill the lower chamber, cover the safety valve, and keep adding until the water line hits the coffee filter basket (that way the oils can be cleaned from there at the same time).

Pour out some of the water. Make sure the safety valve is no longer covered—you’re about to do a plain water brew cycle and want the valve to work if needed.

While the process takes a few hours overall, there’s really only 5-10 minutes of hands-on cleaning—and it goes a long way. Now your brew will be untainted by old grounds, your moka pot won’t have a faulty valve, and you can brew will complete confidence.

I bought a Bialetti Brikka (new-ish version with black bottom but still with the gravity valve) in 2020 for my Covid-Coffee and it was an okay quality. Still lots of aluminium chaff flying around everywhere, definitely needed more cleaning than Bialetti says is “permissible” because dish soap supposedly harms the metal (not true).

The valve is simply a rubber membrane that is not sold as a replacement part, have fun with that I guess. So much aluminium dust and shavings everywhere, even in the valve, where the consumer should never look I guess. The paint on the bottom is even worse than on my old brikka.

And to top it all off, I am not even sure if that valve rubber is silicone or not (confusion with old Bialetti descriptions since the gravity valve Brikkas all had a clear silicone nozzle to constrict flow against the valve). The new valve rubber is white like the main gasket (which is natural rubber IIRC), so have fun when that gets icky and there are no replacements (it’s a rather complex moulding with a tapered inside ending in a slit which gets compressed by the top part of the valve).

I will get my 45€ back and invest that in a cheap espresso machine (I didn’t want to make 4 cups with my old Bialetti all the time, so this should be worth it).

For fans of a rich, bold cup of coffee, it’s hard to go past the Moka pot. These humble coffee makers have been a staple of the Italian kitchen for decades, brewing espresso style coffee without the expense and hassle of a large machine.

Whether you want a designer model or something you can take on the road, there’s a Moka pot for you. Here’s what you need to know before you buy, and some of the best stovetop espresso makers around.

This stovetop coffee maker garnered plenty of good remarks from happy customers, and it’s no wonder why. Designed in Italy, this high-quality ‘moka express’ comes in a variety of sizes, so you can choose according to preference. It also makes coffee fast without sacrificing quality or style.

You should already know that Moka pots won’t brew espresso like an espresso machine will. But they still make a damn fine, strong cup of Joe (1). If you want to get it right the first time, consider the following points when choosing a stovetop espresso maker:

While some claim that the highest quality percolators are made in Italy – which is no wonder, they are often simply called Italian espresso pots or ‘Bialetti’s’ – we don’t find this necessarily to be the case. On average, it’s fair to say that whenever it says ‘Made in Italy’ you can be rest assured the quality will be great, while China is more of a mixed bag. To boot, having an authentic Italian stovetop espresso maker does add to the charm a bit, doesn’t it?

For the solo coffee connoisseurs among us, the brew-a-cup-at-a-time Moka pots are the perfect fit. But, if you plan to share a cup with your partner or friend, choose one that can make more than 1 brew per use – there is nothing more annoying than having to repeat the process multiple times for multiple coffees.

Stovetop coffee makers or Moka pots come in various sizes. Here’s a useful size chart to follow when deciding on the amount of liquid you need from your Moka pot:

Remember that not all Moka pots will work with an electric stove. Be sure to check whether the one you’re considering is electric or induction stovetop friendly. We’ve found that glass-topped electric stoves typically work beautifully, and very quickly, with Moka pots.

The traditional moka pot is made from aluminum – the material is light, cheap and great at conducting heat or, to keep it real for us caffeine fiends, brewing coffee. But, you’ll find that many manufacturers now include percolators made from stainless steel. And for good reason. A stainless steel moka pot looks much sexier in your kitchen plus the material racks up some major advantages when compared to aluminum (2).

Until recently, Moka pots were the only way to get an ‘almost espresso’ without a machine. Today, there are plenty of other options for making an espresso-like coffee or an actual espresso without a machine. For instance, various portable espresso makers are available for everyone’s pocket. So why do people still use stovetop coffee makers?

Moka pot is hipsterish, retro, and, honestly, very convenient to use. Like the Aeropress, the Moka pot doesn’t produce an actual espresso. But moka coffee is still rich, thick, and creamy. Basically, it’s an affordable way to enjoy beautiful coffee and feel like part of Italy’s long tradition of coffee drinking.

Based on customer reviews in the US and our own experience with the cowboy method, Home Grounds searched for the best Moka pot on the market. The table summarizes features, and below you’ll find more detailed reviews of the best ones we’ve found in the market:

Bialetti is the number one player in the stovetop espresso maker market, which is not a surprise once you see the thousands of happy customer reviews on their Moka pots. Due to its features, the Bialetti Moka Express has long been dubbed as one of the best coffee makers. The octagonal shape of the coffee maker allows the heat to distribute perfectly while your coffee brews, resulting in a strong Moka pot coffeein under 5 minutes (4).

Once you’re done, clean-up is easy thanks to the compartment design; just unscrew it, wash it, and get on with your day. The Italian-made ‘Moka express’ range is so popular that they made it available in 1, 3, 6, and 9 cup options – so choose the right size for your preference and you’ll start your day with the perfect amount of coffee.

I personally only use this Moka pot nowadays – I’ve been through other models and the consistency you get is unbeatable. Read my Bialetti Moka Express review if you wish to learn more. The Bialetti Brikka, a modern alternative to the Moka Express is also worth checking out.

The Bialetti Venus features soft lines and a harmonious design that gives it just as the name suggests an elegant look. It’s a beauty to the eye. It also produces great tasting coffee. Its stainless steel construction means it’s suited for induction cooktops. The handle is insulated to resist high temperatures, hence you can use the unit without having to worry about burning yourself when pouring.

This moka pot is available in the biggest range of sizes, with 1, 3, 6, 9 and 12 cup versions available – in a choice of black, chrome, white, red and blue.

As with the French press, percolator coffee tends to have a few grounds, especially as you near the bottom of the pot. But again, fans of percolators like the way it doesn’t filter out the oils as it brews coffee. If the grounds bother you (they’re not everyone’s cup of tea – pardon the expression), 3.5″ disc filters help solve that problem. Just slide one down into the brew basket before adding your coffee.

The bulbous design, which is supposed to represent a baby bird, helps to stop filtration at precisely the right moment. Even if the moka pot is left on the heat, the coffee won’t develop the burnt taste that is often problematic with stovetop coffee makers. The unique v-shaped spout (the chick’s beak) provides more accurate pouring and fewer drips.

Moka pot users tend to time their brew by ear. When you hear a rumbling or gurgling noise, this is a signal that the last of the coffee is making its way up through the tube and it’s time to turn off the heat.

The glass does mean it’s not going to withstand a drop to the floor, but apart from that, the Geesta functions as any other moka pot would. The filter basket, base and lid are made from stainless steel, so it’s both dishwasher safe and suitable for induction stove tops.

One of the appealing things about buying a Moka pot is that there is a model to suit almost any need or budget. For Home Grounds, the Cuisinox Roma stands out for its build quality, elegant design, and the fact it works with a wide range of stove tops. It’s not cheap, but with a 25-year guarantee, you might never need to buy another.

You can use your favorite kind of coffee blend (beans) in a stovetop espresso maker. It’s recommended that you grind your coffee fresh at home and use a grind size slightly finer than you would for drip coffee and a little more coarse than that for an espresso machine. Don’t use extracts, instant coffee, or infusions in your stovetop maker. Here’s a guide on the best coffee for moka pots.

Stovetop espresso is good but not as good as a connoisseurs-like espresso. Though the results don’t quite live up to the real deal, Moka pots are a convenient home-brewing alternative producing a thick, strong, and delicious cup of coffee. It’s easy to over or under extract your grounds using a stovetop maker but, you should know, practice makes close-to-perfect (espresso).

You can clean a stainless steel Moka pot using one part white vinegar and two parts cold water. Pour the water and vinegar into the basin of the pot and turn it on. Brew a full pot and let the solution sit for 15 minutes. Then, empty the pot and rinse with cold water. Or, use a combination of baking soda and cold water for a simple clean (no brewing here!).

So you want to learn how to use a stovetop espresso maker? Here are 7 steps to perfect Italian Moka Stovetop espresso coffee! A stovetop espresso maker is also called an Italian coffee maker, moka pot or a coffee percolator.

Stovetop espresso makers were first introduced in 1933 by Alfonso Bialetti in Italy. It is generally called an Italian coffee maker, or a Moka pot. It is a type of Italian percolator for making stovetop espresso coffee.

The highest quality stove-top espresso makers have Italian safety valves. These safety valves make sure the coffee percolator can withstand the high water pressure that develops during the brewing process.

The hot water goes through the coffee grinds and into the top chamber. The steam brewing water gives a bold coffee flavour. This way an Italian stovetop coffee maker brews a thick and rich Moka coffee. Also commonly known as Italian espresso.

What is the actual liquid capacity of each size of moka espresso coffee maker? View our GROSCHE Milano stovetop espresso maker page for this and more information about moka pots.

Safety tip!  Don’t fill water above the safety valve. The safety valve is there to release pressure in case the pressure is too high. That can be due to any blockages.

The safety valve avoids a possible explosion of the pot from high pressure. Make sure the stovetop coffee maker you use has an Italian safety valve. Some coffee percolators use cheap valves that can lead to dangerous accidents while making coffee. Check out the MILANOif you’re interested in buying one.

The best way to clean your stovetop espresso maker is using warm water and a tough sponge. They say the older a moka pot gets the better its coffee tastes. And using soaps remove the conditioning that a moka pot gets with time.

Detergent is not necessary and also not recommended. That is why they say that the older these coffee makers get, the better the coffee tastes. You may have heard that in Italy grandma’s Moka espresso maker is the prized possession of the family.

So if you find any build up or if the seal appears to be damaged, it’s time for replacements. Usually, the seals should be changed every 6 months. Also if you are a heavy user of the Moka pot you may need to replace them more often.

There are three common sizes to the espresso maker gaskets. The seals come in 3, 6, or 9 cup sizes and are mostly universal in their fit. You should carefully remove the seal in your espresso pot and measure it and compare to the chart below. Then you can select the right one to buy for your Moka pot gasket replacement.

The Bialetti Brikka Stovetop Coffee Maker is an aluminum Moka Pot that utilizes an innovative "Brikka-System" system to consistently deliver delicious, rich stovetop coffee with a wonderful aroma. Bialetti’s patented dual safety valve ensures perfect froth every time by regulating the pressure of water flowing through grounds for a richer-tasting coffee.

Maybe your moka pot is hissing and spitting steam or your coffee is too weak. Here are the ways to fix the most common problems with a Bialetti to make sure your morning brew is everything you expect.

Three possible reasons: Either the safety valve is clogged, you’ve filled the reservoir above the fill line, or the filter may be clogged up so that the water isn’t escaping into the jug part of the pot as it should.

What to do: Take the whole pot apart, including the gasket and filter, and rinse thoroughly, wiping off any stray or stuck coffee grounds with a sponge. Also, check to see if your safety valve has a tiny protuberance (like a little metal stick that you can push from the inside)—some of my older pots had this, but my newer one doesn’t. If so, push this in a few times (it springs back again) to dislodge the blockage. If the problem continues, you might have to send the pot back or buy a new one, depending on whether it’s still under warranty.

It"s not hard to make a great cup of coffee with these machines, but there are specific things you must do, including seasoning it, loading it properly, and keeping it clean. Read How to Make Perfect Stovetop Espresso Coffee With a Bialetti Moka Pot to learn more.
