I have a flow control valve like this:
http://www.grainger.com/Grainger/PAR...789?Pid=search
It controls the speed of a 2x10 cylinder and the movement of the cylinder
and mechanism is making the adjustment knob move so the cylinder gets
faster and faster. It does have a set screw that will lock the adjustment
knob but the operator needs to change it often and during the stroke. Is
there a simple way to stiffen the knob without locking it? (Yes, I could
get a new one.)
