Valve Packing Demonstrator

#250

This detailed replica of a 6" gate valve, with backseat, facilitates training in the proper removal and installation of packing. A clear acrylic stuffing box allows total visibility of the packing area, both during maintenance activities and after compression. The natural magnification created by the acrylic housing shows "consolidation" and packing pressure against the cavity wall clearly. Water and coloring can be introduced to see migration due to insufficient gland load, improper installation techniques and stem/cavity imperfections. Ideal for demonstrations in the use of die-formed graphite packing, modern packing materials and live loading, this device helps promote professional maintenance habits and takes the mystery out of the function of packing systems.
