WebMar 8, 2012 · It indexes valve Cv against cylinder bore size and gives the resulting cylinder speed in inches of stroke per second. It assumes a pressure of 80 psi and ΔP = 80%. To … WebMar 8, 2012 · It is generally used to compare flows of different valves: the higher the Cv, the greater the flow. To match a valve and cylinder, the following equation gives the Cv (valve flow) required for operating a given air cylinder within a specific time interval. Cv = (A × S × a × Cf) ÷ (t × 29) where A is cylinder piston area. (π × r2), in.2;
