I made a demo board up in December that used a flow control from a previous year. I attached the flow control to one exhaust port on a 5-port 2-way single solenoid valve, rather than directly onto the cylinder. The valve slo-o-o-wly extended, then snapped shut like a mouse trap.
If the flow control only acts as a control for air going from the push connection to the screw in, and acts as an open tube for air coming in the screw in, and flowing out the push in, then the above could never have worked: the air was going from screw in to push in, and was flow controlled.
Obviously, this valve didn't work the way someone has suggested earlier in this thread: are this year's flow restrictor valves different from those issued in the past ?
