摘要： The disclosure relates to exemplary embodiments for a combination device configured to effect lockout and partial stroke testing for an actuator having a piston rod providing linear motion and connected to a guide block in an actuator, wherein the combination device includes a device housing having a housing bore, wherein the device housing is adapted to mount on a receptacle on the actuator that aligns a device housing bore coaxially to the translatory motion axis of the piston rod; an extension rod attached to the guide block connected to the piston rod; at least two slides or a profiled bore index sleeve disposed in the device housing that when engaged provide means of restraining the movement of the extension rod in a manner that prevents said extension rod and a driver element of the actuator from rotating, relative to an actuator housing; a housing cover mounted over the device housing wherein the housing cover protects and retains the extension rod, and the slides or the index sleeve in the device housing and a spring biased safety pin mounted on the housing cover wherein the spring biased safety pin is configured to prevent unintended actuation of the actuator; and a tubular cover to protect the extension rod.
