I get how the bulb controls the valve and I understand the equalizer tube measures or you can say senses the evaporator pressure. But how does the spring at the bottom come into play?
I'm a student and just starting to learn this stuff so go easy!
1-Remote bulb pressure
3-Superheat spring equivalent pressure???
When they say "Superheat spring pressure" is this set at the warehouse and then adjusted in the field based on the techs reading? (This is what I'm assuming) Also, If I'm wrong on the equilizer tube please say so.
