Hi guys,

Anybody who knows whether or nor there is a check valve (non-return) beneath the A/C safety pressure valve?
...meaning that you don’t have to evacuate the system, if the safety pressure valve needs to be replaced?

The picture is just a screenshot from a Google-search.

All the best
Kasper
