NOTE
• For gas service, multiply values from Table 1 by 1.5.
• Consult the factory for instructions regarding use in square or
rectangular ducts.
• “In Plane A” means the bar is in the same plane as the elbow.
“Out of Plane A” means the bar is perpendicular to the plane of
the elbow.
• If proper lengths of straight run are not available, position the
mounting such that 80% of the run is upstream and 20% is
downstream.
• Use straightening vanes to reduce the required straight run
length.
• Row 6 in Table 1 applies to gate, globe, plug, and other
throttling valves that are partially opened, as well as control
valves.
