ABSTRACT:
An actuator-cylinder valve connection mechanism has a bonnet nut with external threads and receives an outer valve stem, a valve body having an upper end with internal and external threads with the internal threads in engagement with the external threads of the bonnet nut, and either a jam nut or an actuator housing of the actuator having a downward extension with internal threds in engagement with the external threads of the upper end of the valve body. Clearances, apertures, and a direct contact of the jam nut or the actuator housing against the top surface of the upper end of the valve body cause any impact or inertial forces to be circumvented from the jam nut or the housing and into the valve body, thereby entirely bypassing the sealing mechanism which is comprised of the bonnet nut.
