Well, we will see how this works. I have tried
modifying a vacuum operated valve so that a cable can operate it. Pictures
attached tell the story.
1. Opened_heater_valve3.jpg shows the result after
I took a 1" hole saw to the heater valve. Pretty much ruined it, but I could
then see how it works. There is a spring to hold the valve closed, and the
diaphram pulls the valve open when vacuum is applied.
2. I then bought another one, and carefully drilled
a 5/16" hole in the center, as shown in Heater_valve_smhole.jpg . The pin
lying by its side has been tapped for 10-32 on one end, and drilled for a push
fit on the other.
3. The pin has been 'JB-welded' to the pin on the
diaphram, and we shall see how well this stands up.
Picture of 3 on next email to stay below
limit.
