The non-return valve contains a movable sealing disc. As the medium flows, it lifts the disk to allow it to flow through the valve. The lift value depends on the amount of flowing medium. If the media flow drops to zero and stops, the disc blocks the passage through the valve and reverse flow is prevented. This happens thanks to a spring that constantly pushes the disk against the flowing medium. However, the pressure exerted by the spring is less than the pressure of the flowing medium, so the valve remains open.
In order to achieve the correct function of the ignition, it is recommended to check it regularly.
