Oops! I was looking at the wrong system! Now I see the point in Woodies qev system, it very clever. So if I understand it right the flipper will fire when you close the solenoid valve as then the pressure will drop opening the qev valve dumping all the gas in the buffertank into the ram then when you open the valve the qev valve will close directing the gas to the buffer tank to fill it up again. Is that right?

Also can you get a qev valve with a flow of 8cv?
