bialetti venus safety valve 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.

How to prepare coffee: fill the boiler up to the safety valve with water, insert the funnel tank and add the ground coffee for moka without pressing; close the moka pot and place it on the hob. Wait for coffee to gurgle as it rises to the collector (upper chamber), turn off the gas and, finally, enjoy your delicious coffee!

A size for every need: Bialetti Venus sizes are measured in espresso cups; coffee can be enjoyed in espresso cups or larger cups, according to your needs. This is why Bialetti Venus is available in different sizes (2 (no induction), 4, 6 and 10 cups). Number of ml per format: 85 ml - 170 ml - 235 ml - 460 ml

How to prepare coffee: to make a great cup of coffee, simply pour water into the boiler up to the safety valve, insert the funnel in the tank and add the ground coffee for moka without pressing it. Close the moka tightly and place it on the hob at medium temperature. Wait for coffee to gurgle as it rises to the collector (upper chamber), turn off the hob and finally enjoy a good coffee!

The most popular of our stainless steel stovetops, the Bialetti Venus produces the same authentic Italian espresso, using the same brewing technique, as the original Moka Express.

This stovetop espresso pot is made from 18/10 stainless steel and is compatible with all cooktops including induction* (Venus 2 cup size is not suitable for induction cooktops).

A functional style with a practical, drip-less pouring spout, it is constructed from food grade 18/10 stainless steel and has an ergonomic, heat-resistant handle with secure anti-slip grip and features Bialetti’s patented safety valve.

To produce an authentic espresso in minutes, simply fill the bottom with water to just below the valve, add your favourite espresso ground coffee to the funnel and gently heat on your stovetop.

Bialetti is a company that invented moka pots. However, today many other brands offer Italian stove top coffee makers for 2 or even 3 times lower price. Is there any real difference between them except the famous ‘little man with the mustache’ logo, which Bialetti proudly put on its models? (Spoiler: yes)

I decided to compare stainless steel versions, since my new kitchen is equipped with a induction stove (classic aluminium moka pots like Moka Express or Brikka can’t work with it). I choose a Bialetti Venus by Bialetti (‘Made in India according to Bialetti’s quality standarts’ was written on the box) and a similar moka pot by some unknown brand from China (almost 3 times cheaper). Both are for 4 cups, which equals to 160ml. Here they are:

So let’s investigate the differences between cheap Chinese moka pot made of steel vs original Bialetti Venus.I will not describe the unboxing process (though Bialetti packaging was better) and focus on the materials, construction, coffee taste and temperature:

Both coffee makers are made of stainless steel. However the thickness of the metal is different, Chinese one definetly has more slim edges (hereinafter on photos the Bialetti is on left while the Chinese one is on right):

The fact that Bialetti uses a lot more metal while producing their stove top espresso makers is also proven by the weight. According to my kitchen scale it’s 544 grams (19.2 ounces) in the case of Bialetti vs 330 grams (11.6 ounces) in the case of its counterpart. Both measurements are made without boxes:

❕ The main thing, that dissapointed me was the weirdly coated bottom section in Chinese moka pot. While the Bialetti has a equaly shiny polished steel both outside and inside, the bottom chamber of the second coffee maker has a layer of some strange material:

My last observation is about emergency valve that is located one the side of the bottom chamber and that is used to lower the pressure if the funnel would be clogged. They are different:

The Bialetti inspection valve is a patented valve, which has been designed to guarantee the use of the coffee maker in complete safety. Using the coffee maker with drinking water entails the risk of formation of lime scale in the hole of the safety valve, causing the clogging of the valve itself and the malfunctioning of the product.

With the Bialetti inspection valve, it is very simple to avoid clogging arising from lime scale: just move the small piston coming out of the valve along its axis when washing the coffee maker.

As I mentioned above the fact that Chinese has thinner metal body affects the brewing proccess. Bialetti’s upper chamber stays cools longer, while all parts of Chinese coffee maker becomes hot very soon. That means that temperature of extraction is higher on Chinese one. It’s generally condidered to be bad for the coffee taste (because it may become bitter), however it’s better for lovers of hot coffee.

Here are photos of coffee temperature measurement in Bialetti Venus and in ATWFS moka pot just after brewing on gas cooker (photos kindly provided by my reader kroleg-m):

Of all the challenges you face keeping your customers’ plants operating at full capacity, safety and relief valves shouldn’t be one of them. NASVI’s job is to give you the confidence that your valve supply chain is rock solid regardless the pressure it’s under.

Bialetti’s legacy of quality and reliability lives on in these lines of coffee makers crafted in high-quality 18/10 stainless with ergonomic, heat-resistant handles. Now everyone can have the beverages they crave and a look they love.

New Venus is an updated version of one of the most popular moka pot models by Bialetti, the world’s leading manufacturer of coffee makers. Compared to the previous version, the new one includes new upper part, lid knob and handle design as well as increased lower part thickness by 20%. Bialetti Venus 2tz model it used to brew 2 cups of espresso at a time (approx. 50ml each). The total capacity is 100ml.

Its streamlined shape and original design make Bialetti Venus a great decoration of every kitchen. This amazing look is combined with functionality. This device is made of polished stainless steel with a black plastic handle. Stainless steel has less effect on the coffee taste than aluminum and the ergonomic shape of the handle allows for comfortable pouring of the prepared espresso.

Bialetti Venus is suitable for gas, electric and induction hobs (4tz size and more). Put the product on the hob so that the handle is beyond the reach of heat.

The coffee maker constists of a top sealed tank, a filter and a bottom tank. Put ground coffee beans in the filter, pour water into the bottom tank below the safety valve level and connect all the elements. Put the coffee pot on the stove and wait a few minutes. Hot water moves to the top tank, flowing through ground beans. Your delicious and aromatic espresso is ready!

For those preferring a smoother coffee taste, Bialetti’s stainless stove-top pots embody our legendary ease-of-operation in sleek contemporary designs.

1. Start by pouring the water at room temperature into the Moka boiler and fill it up to the level of the safety valve. Do not exceed this level to avoid obtaining a coffee that is too watery.

The looks of this specific Bialetti Venus model is quite different from the original octagonal shape, but the inner workings are the same. The main difference is that the Venus is also compatible with induction cooktops, by using stainless steel instead of aluminium as build material. The design is a little more modern, and even though a lot less iconic, I still like the look of it.

We now pour boiling water into the bottom compartment, all the way up to the safety valve. The safety valve will release excess pressure to avoid this devices blowing up. This is actually one of the downsides of this machine, for creating such a steam based pressure vessel in the middle of your house is quite a scary thing.

The main downside for me would be the cleaning process. Where the aeropress produces a puck that is easily ejected, and even the flair producing a "knockbox removable able" puck, the bialetti filter doesn"t let go of the grounds that easily. I have found that you need a combination of shaking and rinsing, where a lot of sludge is only removed in the rinsing part.

The most popular of our stainless steel stovetops, the Bialetti Venus produces the same authentic Italian espresso, using the same brewing technique, as the original Moka Express.

A functional style with a practical, drip-less pouring spout, it is constructed from food grade 18/10 stainless steel and has an ergonomic, heat-resistant handle with secure anti-slip grip and features Bialetti’s patented safety valve.

To produce an authentic espresso in minutes, simply fill the bottom with water to just below the valve, add your favourite espresso ground coffee to the funnel and gently heat on your stovetop.

1. Fill the base with water to just below the level of the safety valve. Be careful not to overfill as the air in the space between the water and the coffee filter is what heats and forces the water up through the coffee. If the water tank is overfilled the result is boiled coffee, with a bitter or burnt taste.

The Bialetti Venus Moka Pot combines beauty and elegance in a tastefully designed stove-top espresso maker with a unique style. The Venus can produce a rich, authentic Italian espresso in just 4-5minutes.

The Venus beautiful stove-top espresso maker body is constructed completely made from high quality 18/10 stainless steel (including all internal parts). The Venus can be used on gas, electric, and induction stoves.

Elegance and performance in a new form promises the revised Bialetti Venus 4 made of high quality 18/10 stainless steel with ergonomic and non-slip handle.
