Differential temp drop across FCU - affects pressure?

Maybe a dumb question...but does the 7degs differential temperature drop give a large pressure increase across the FCU coil and ultimately the return leg?

If this is correct - would a differential pressure control valve help to control this increase ?

Basic answers please!!

Many Thanks

Having trouble undersanding what your asking here.

Are you saying your evaperating coil has 7 degrees diffrence from inlet to outlet?

Could you define return leg?

A TEV will automatically adjust to maintain superheat.

no not correct, you need proper air balancing
