I just found this great resource on youtube from a university in India. It has video recorded a tremendous amount of courses and put them online. Below is a 2 part course on control valves…

Also here is a video from a different course on control valves..
This photo is from a group in England that shows young ladies how to work on maintenance issues on a ship. Very interesting and funny. I also found a great link to a video on valve packing installation from a training group in Canada.
They have a long list of videos here.
Below is part 2 of the video going over how to install the main components of the Chesterton valve sealing system. This video has also been updated to include the latest installation techniques.

This is a photo that a friend of mine took of a large MOV (motor operated valve) in a fossil power plant near Chicago. It had been packed with our valve live loading system for almost 20 years. It never leaked during that time and it would still be going but they re-packed it to inspect the stem.
It also is a good visual of valve orientations ~ as you can see, this valve is somewhere between horizontal and vertical. At its mounted angle it is very critical that the valve does not leak since it would ruin the motor.
