In fact, there is no need to worry about single valve or double valve, because the safety valve of mocha pot is 4bar, so it is enough to make coffee at home. Even the double valve can't reach the pressure above 9bar of the coffee machine, and it can't produce the super-thick grease produced by the coffee machine.

Mocha pot is a tool to extract the basis of espresso. Because of the convenience of making coffee, it began to spread in Italian families, and later gradually developed into an Italian national product, which has now been sold all over the world.

Working principle:

Mocha pot is made of aluminum or stainless steel and is divided into upper and lower parts. The middle is connected by a conduit, and the pot below is used to hold water. The pot body has a pressure relief valve, which will automatically release the pressure when the pressure is too high.

The working principle of mocha pot is that the pot is heated on the stove, and the water at the bottom of the pot is converted into steam after boiling. Using the pressure generated by volatile steam when water boils, hot water is pushed into the powder pot filled with ground coffee from the conduit, filtered by the filter screen and flowed into the upper pot.
