Abstract
A system for securing a valve actuator to a valve assembly includes an actuator housing with a plurality of housing lugs protruding radially. A cylinder assembly is located within the actuator housing and has a horseshoe connector to engage a valve stem nub of a valve stem and transfer axial movement of the horseshoe connector to axial movement of the valve stem. A bonnet has a plurality of bonnet lugs protruding radially from the bonnet to define a plurality of bonnet slots therebetween, wherein each of the plurality of housing lugs are sized to pass axially through a respective one of the plurality of bonnet slots when the actuator housing is in a released position, the actuator housing being rotatable to a locked position such that the plurality of bonnet lugs prevent axial movement of the actuator housing in at least one direction.
