Design and Function:
One-Way Valve Mechanism: The valve is designed as a one-way system, allowing gas to exit the package but preventing air from entering. This mechanism is essential for maintaining the freshness and quality of the coffee beans by creating a controlled environment inside the package.
Integrated Filter: Often, these valves include a filter element that prevents coffee particles from clogging the valve while allowing gas to escape effectively.
Pressure Release: When the internal pressure inside the coffee package exceeds a certain threshold due to CO2 buildup, the valve opens to release the gas. This prevents the package from becoming over-pressurized and ensures that the coffee beans remain intact without compromising flavor.
Materials and Construction:
Food-Grade Materials: Coffee Venting Aerofluxus Valves are typically made from food-grade plastics and/or metals that are safe for contact with coffee and do not affect its taste or quality.
Sealing Capabilities: The valve is engineered to provide a reliable seal against oxygen and moisture ingress, thereby preserving the aroma and freshness of the coffee beans over an extended period.
Preservation of Freshness: By allowing CO2 to escape while preventing oxygen entry, the valve helps preserve the freshness, aroma, and flavor of the coffee beans.
Extended Shelf Life: Effective management of gas release extends the shelf life of coffee, ensuring that consumers enjoy a high-quality product even after storage.

1. 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.
2. 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.
3. 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.
