Thanks for that info Chris.
You say you have the valves (plural) modeled. Could I ask you to re-run the model with the exhaust (retract) side of the piston vented directly to atmosphere, with no valve or fitting? GDC seems to have ruled this legal:

You wouldn't have to change the model, just use some large value for the Cv and diameter on the exhaust valve and tubing.
