Actually, if you dismantle the more recent Facets, there is a minute groove scribed into the nylon?? valve faces. I think this allows a titchy amount of fuel to drain back across the face when not in use to keep it lubricated and stop it getting stuck. Eventually they will leak backwards albeit very very slowly.
