Valve Response Charts
The charts below represent the fill and exhaust times for each of the various sizes of DM

Series D
double valves. The “fill” times were measured while raising (filling) the pressure in a volume from 0 to
30, 60, & 80 psi (0 to 2.1, 4.1, & 5.5 bar) with a 90 psi (6.2 bar) inlet pressure. Conversely, the “exhaust”
times were measured while lowering the pressure (exhausting) in a volume from 90 psi (6.2 bar) down
to 90 to 60, 30, & 9 psi (4.1, 2.1, & 0.6 bar). Exhausting tests performed with silencer installed.
