Bonnet apparatus to provide live-loading to a seal are described herein. An example bonnet assembly includes a housing having a recessed opening to define a shoulder and a sealing disc disposed within the recessed opening. A biasing element is disposed in the recessed opening between a flange of the sealing disc and the shoulder of the housing to provide a load to a seal to be disposed between the housing and the fluid device. The biasing element biases the sealing disc away from the housing and the biasing element enables the sealing disc to move within the recessed opening relative to the housing when the bonnet assembly is coupled to the fluid device. |
