If the circ. is pumping away from the boiler and the expansion tank and it has a check valve, I use taco sentry zone valves and spring check valves on the return do I need a flow control valve to stop ghosting

How is it piped?
Unless you have very large diameter pipes, I am not sure why you need any check valves. The zone valves will prevent flow when the zone is not calling. The main circ only needs a check if it is opposed by another circ.

piped
going to run 1 1/4 out into micro bubble than to tee 1 to circ for indirect with spring check on return to boiler, after the tee the main line will have the main circ for the zones going up still in 1 1/4 to the zones taking off in 3/4 with ball valves. At the end of the zones will be taco sentry valves going back to 1 1/4. This will go down to boiler with a spring check were the return for the HH will meet then both go into boiler. the water feed will be on the bottom of boiler with the drain. I have not decided on putting the expansion tank on the boiler or the bottom of the bubblier, leaning on the boiler by the PRV.0 -
Check valves
It sounds like the circulators need check valves.The zone valves will suffice for the zones. I don't know why you would add the zone checks.

checks
So you are saying with zone valves and checks in the circs I dont need any check valves installed...0 -
Checks
If I understand your description correctly, that is all you need. Post a sketch if you want to be sure.

Check valves
You only need checks at the circulators with that arrangement."If you can't explain it simply, you don't understand it well enough"
