Quick Release Valve

We are going back and forth about whether the rules allow the use of quick release valves. Any thoughts?

Do you have an example of a quick release value you would like to use? Certain 3-way quick exhaust valves are legal this year, provided they still allow all air to be vented when the main release valve is used.

We would like to use a Clippard JEV-F2F2 Exhaust Valve that would allow us to fire a cylinder. It would also allow all air to be vented by the main release valve.
