New One Way Gusted Plastic White 0.82 g Per Valve Bialetti Valve For Keep Coffee Fresh

Product Description : 

The Bialetti pressure valve, commonly found in Bialetti stovetop espresso makers such as the Moka Express, operates on a simple yet effective principle known as pressure relief or pressure release. Here's an explanation of how it works:

Steam Pressure Build-Up: When you brew coffee in a stovetop espresso maker like the Moka pot, water is heated in the bottom chamber. As the water reaches boiling point, it generates steam. This steam builds up pressure inside the sealed chamber.

​

Pressure Threshold: The Bialetti pressure valve is designed to release excess steam pressure when it reaches a certain threshold. This threshold is carefully calibrated to ensure that the pressure inside the pot remains within safe limits during the brewing process.

​

One-Way Valve: The pressure valve is essentially a one-way valve. It allows steam to escape from the Moka pot when the pressure inside exceeds the set threshold. However, it does not allow air or liquid to enter from the outside.

​

Maintaining Brewing Conditions: By releasing excess steam pressure, the pressure valve helps maintain consistent brewing conditions inside the Moka pot. This ensures that the coffee grounds are properly extracted and that the resulting espresso is flavorful and aromatic.

​

Safety Mechanism: The pressure valve serves as a safety mechanism to prevent the Moka pot from becoming over-pressurized. Without proper pressure regulation, there could be a risk of the pot exploding or malfunctioning, leading to potential safety hazards.

​

Automatic Operation: The pressure valve operates automatically during the brewing process. As steam pressure builds up inside the Moka pot, the valve opens to release excess pressure. Once the pressure drops back to a safe level, the valve closes again.

FAQ  : 

1. What is coffee One Way Degassing valve?

One way degassing coffee valves are vital to maximizing freshness by allowing freshly roasted coffee to degas in the package. Our one way degassing valves are industry proven to effectively and effectively vent CO2 gas build-up while sealing out environmental oxygen, moisture and contaminants.

2. Can the coffee valve customized to allow air to escape more quickly for larger package?

We can also custom fabricate valves to meet specific requirements.

3. Can one way degassing coffee valves be used under water?

We do not recommend that coffee one way degassing valves be used while immersed in water.

4. What is the purpose of silicon oil? How does the performance change without the silicon?

It is so that air will not come back in after a while. Most products packaged with valves are sensitive to oxygen and moisture, and the silicon oil ensures that it functions as a one way degassing valve.

5.Why is the Bialetti pressure valve leaking or dripping during brewing?

 If the pressure valve on your Bialetti Moka pot is leaking or dripping during brewing, it could be due to several reasons, including overfilling the   water chamber, blockage or debris in
