Flow vs. Pressure Drop
Table 1 indicates the pressure drop through both channels of the by-pass valve at various flows at 100 psig (7 bar). For pressures other then 100 psig (7 bar) multiply pressure drop
from Table 1 at the required flow by the pressure correction factor from Table 2 that corresponds to your system’s operating pressure.
For example: With the valve on line and flow at 5 scfm and system pressure at 125 psig, find corrected pressure drop by multiplying 0.19 from Table 1 by 0.82 from Table 2. The
pressure drop at these conditions is (0.19 x 0.82) = 0.16 psid. To find pressure drop through valve in by-pass mode divide corrected pressure drop by 2. In this case pressure drop
in the by-pass mode would be 0.08 psid.
