c DANGER: Before installation check the order no., serial no., and/or the tag no. to ensure that the valve/actuator is
correct for the intended application.
Prior to assembly, manually open and close valve (if possible), to ensure freedom of operation. Be sure valve and
Limitorque actuator rotate in the same direction and are in the same position (i.e., valve closed, actuator closed). The
assembly position of the actuator, with reference to the valve, has to be in accordance with the plant requirements
(actuator axis parallel or perpendicular to the pipeline axis).
