Rotary high-vacuum gate valves use a thin layer of gas to separate a rotating valve member from a stationary member. bearing vacuum valves rely on the conductance of the very small separation between members (i.e., the ability of gas to flow through a small slot) to seal a high vacuum chamber from room environment.
