Note
If used in safety relevant applications, additional measures are necessary, e. g. in
Europe the standards listed under the EU machine guidelines must be observed.
Without additional measures in accordance with statutory minimum requirements, the
product is not suitable for use in safety-related sections of control systems.

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.
