Abstract
Example aspects of a method of using a bonnet and stuffing box assembly and a method of manufacturing a bonnet and stuffing box assembly are disclosed. The method of using a bonnet and stuffing box assembly can comprise providing a stuffing box, a bonnet, a bushing assembly, and a stem, the stuffing box and the bonnet defining an assembly bore, the bushing assembly received in the assembly bore, the bushing assembly defining a bushing bore, and the stem received through the bushing bore; sealing the stem relative to the bushing assembly to prohibit fluid flow through the bushing bore; sealing the bushing assembly relative to the bonnet to prohibit fluid flow through the assembly bore; and turning the stem relative to the bushing assembly, bonnet, and stuffing box to actuate a valve.
