2052 Actuator
November 2011
2
A top-mounted handwheel option is available for infrequent service as a manual actuator. For repeated or daily manual
operation, the unit should be equipped with a side-mounted declutchable 1078 manual actuator. Externally adjustable
travel stops are used to limit the degree of rotation at both ends of the actuator stroke.
The lever for the 2052 actuator is supported by bushings. The lever may be changed to accommodate valve bodies
with different size valve shafts.
