Tech Tips for Thermostatic Expansion Valves
Thermostatic Expansion Valve |
You are writing for a T shaped expansion valve with the sensing capillary tube, Which you are 100% correct for.
This one is an H block. and the sensing tube passes through the suction port in it. This one is actually showing a little tail of the same capilary sticking out - I think its used for something on the production line - some dont even have it anymore - all you see is a flat rivet.
