I have one of the Tisco style dual remote valves.
It has a screw on the front that is marked "quick drop" or similar.
Does that screw adjustment also make one pair single acting?
Back story - one pair of hoses works in dual acting mode, the other
pair does not. Only works one way. I need them to work both ways.
The screw is stuck solid. I can't turn it. I've tried an impact driver
and penetrating oil, etc. Can I heat it without burning out seals?
I don't want to ruin the rest of the valve as it seems to work
perfectly well other than the one pair of hoses being single acting.
The second handle was replaced after this picture was taken.
