Flow Coefficient of Select Valves

[Jimmy K]

Has anyone measured the flow coefficient of their piston valves? I would be very curious to see how much higher the cv of a piston valve is compared to a the cv of a modified sprinkler valve with equivalently sized ports for a given amount of air (same pressure, temperature, and volume).

I would also be interested in the flow rates of barrel sealers vs. chamber sealers, as well as piston travel distance and piston weight. Does anyone have quantitative data on these aspects of piston valves?

I did some performance matching to see what range I was getting with mine.

It is not "measuring" the valve, but it did give a performance range to match GGDT graphs.
