WARNING
Before carrying out this procedure verify that the
torque limits and basic actuator parameters are
correctly set to prevent damage to the valve.

Torque
The actuator can be set to apply its selected output ‘Torque’
to the valve at the end of travel where tight shut off is
required.
Limit

applied to the valve seat or end of mechanical valve travel.
