What type of valve to balance 1-pipe CH circuit?

Also they present less of an inherent flow restriction.
although in this case, it's there for flow restriction!

True, but the reduced bore ball valves for instance present an "inherent"
flow restriction before you start throttling. So the control offered will
be over a smaller range. Yes I know the purists will say that ball valves
shouldn't be used for flow control!
