Richdel reverse engineering fixes jar top valve

Only a few original 204A jar top valves are working today. A problem cropped up with the stainless steel tube that had the dual role of metering/guide pin and solenoid seat. The tube was shifting position. A slight upward shift in tube position could prevent the valve from opening.

In a neat bit of problem solving, Richdel designed a new bonnet for the valve that worked with a shorter metering tube that no longer needed to be in any precise position. They noted this difference with the word "Floating" in the retrofit kit. The kit included a new bonnet, a new metering tube, and a special tool designed to fit the new tube to the valve body. They also threw in a new solenoid plunger, since they'd recently revised its design.
