Abstract
The present invention relates to a compressible bladder for easing the process of opening a pressure-sealed chamber. The valve comprises a valve body having an interior, wherein media is adapted to flow therethrough; a bonnet defining a chamber carried by the valve body; a plug having a first position and a second position, wherein the plug prohibits media to flow through the valve body in the first position, and the plug does not prohibit media to flow through the valve body in the second position; an elongated stem adapted to move the plug between the two positions, wherein the stem is positioned between the valve body and the bonnet; and a compressible bladder positioned in the chamber of the bonnet adapted to compress upon an increase of pressure within the chamber of the bonnet.
