  • Patent number: 5503406
    Abstract: A valve having an assembly for live loading of the packings of the valve. The assembly includes a plurality of large belleville disk springs arranged such that the shaft or stem of the valve extends through the center of the belleville springs, with threaded studs arranged symmetrically with respect to the valve shaft also extending through the belleville springs. Utilizing the larger spring arrangement, a smaller number of springs are required, and favorable deflection characteristics are provided. Preferably, a compression ring is provided having a portion extending up through the belleville disk springs, with this portion including a visual indicator thereon which provides a visual indication that a desired load is achieved as the springs are loaded via hex nuts provided on the threaded studs of the valve assembly.
