Valtek Mark One Valve Packing Assembly Animation

The Mark One valve is typically double top-stem guided and
completely avoids contact between the plug and seat retainer.
Many globe valve maintenance problems can be traced to cage guiding. The close metal-to-metal contact between the cage and
plug often result in galling and sticking. The Valtek design avoids this potential problem.
