ABSTRACT:
A fluid valve includes a packing element surrounding a valve stem extending through the valve body. A packing flange is adjustably supported on the valve body for moving a follower to compress the packing element. A set of disc springs is supported in a cavity internally of the follower between upper and lower parts to compensate for temperature variations causing volumetric changes in the packing element.
