Function components of Live Loading System

The Proload Live Loading System assembly fits over the existing gland bolts and needs to be tightened at installation till the visible assembly gap closes.
During operation it works as an indicator if wear or consolidation appear and the Proload Live Loading assembly needs to be retightened to its optimal set point. A torque wrench is not required. The feature of Proload Live Loading is to automatically adjust the gland and keep the packing set under constant pressure.

Further components

The carbon restriction bush is made from a high purity material with > 99 % C content with high compression strength. Precisely machined tolerances narrow the gap at the bottom of the stuffing box to a minimum and offer some bearing area for thinner and horizontal orientated valve stems. The length of the bush is readily made up to a depth utilizing the optimum amount of packing rings for best sealing performance and low friction of the stem as a result acknowledged by leading studies. 

Form of delivery

The complete kit includes a die-formed five ring packing set, an axially split carbon restriction bushing and two preset Live Loading Cartridge assemblies. As all sealing components are split they will be installed in the stuffing box without removing the actuator thereby simplifying the installation in the field.

Characteristics

  • This Hybrid Control Valve packing design combines the safety against extrusion provided by the Inconel matrix reinforced eGraphite Yarns and the pliability of Carbon Fiber reinforced eGraphite Yarns, integrated with the low thermal expansion and flexibility of expanded Graphite. The 5-Ring Sets create the optimum sealing configuration for long term reliability even in temperature cycling situations.
  • The external packing rings contain an ultra thin inconel wire matrix to eliminate extrusion. All the rings utilize an inorganic passive corrosion inhibitor to protect against valve stem pitting. All rings are die-formed for exact fit and increased sealability.
