The compressed air is interrupted in the basic position of the valve (1). The air in the table is locked in
and the movement stops. The speed at which the table comes to a stand depends on the mass mo-
ment of inertia and the angular velocity (division). It may therefore happen that the table moves into
its end position but without additional tightening torque. The table can be moved by hand within a
certain range.
