Bosch aroma protection valves are based on patented and proven venting technology to protect aroma and maintain quality of degassed products, sensitive to oxygen. They protect against excess pressure in airtight packaging and eliminate the intermediate storage of degassing products.
The valve is applied on the outside of the bag or tin and functions with slight increase in pressure. Depending on the product requirements, the outside valve has different designs, such as for cans or for a highly degassing product.

Optimum aroma and quality protection for degassing and oxygen-sensitive products, such as
Given increasing overpressure, the membrane is raised higher at one part of the valve until it forms a channel in the fluid, through which the gases can seep to the outside.
