La Marzocco GS/3 Exhaust Flow (non-conical valve)

Описание к видео La Marzocco GS/3 Exhaust Flow (non-conical valve)

This is a video to show that despite the rotary pump delivering nine bars of pressure, the excess pressure not making it to the puck does not need to go anywhere and is retained by the seals on the Rhyton shaft. Users of the new 2017 GS/3 with the conical valve are reporting significant flow out of the exhaust port when doing slow pre-infusion.
