Scope of these instructions:
These instructions are valid for multi-turn actuators of type ranges
SAI 6 – SAI 100 and SARI 6 – SARI 100 for use in Inside Containment of
nuclear power plants.
These operation instructions are only valid for “clockwise closing”, i.e.
driven shaft turns clockwise to close the valve.
