Standard Installation
The following procedure refers to standard yoke-type bonnet installation. It is
important to remember that regardless of the type of yoke, the positioner must
operate within the angle range of -30° to +30°, totaling 60°.
If the positioner operates with an angle smaller than ± 30° the accuracy will be
considerably affected.
1 - Perform a test by applying compressed air directly to the valve through a pressure
regulating valve. To check the maximum and minimum stroke, start by applying 0%
(valve closed). Slowly increase the pressure until the valve reaches 100% of its stroke.
