How to maintain the air non-return valve on S3

The S3 satellite has 2 non-return valves for air: One connected to the outlet of the pressure regulator and one to the air nozzle. The valve connected to the pressure regulator must be replaced once a year. The valve connected to the air nozzle (see image) should be serviced once a year.
