HVAC system piping are usually designed based on velocity limits to
avoid pipe erosion, cavitaon and noise issues. As seen below, the
table has been developed using the MRV (Maximum Recommended
Velocity) limits of 7 /sec to allow piping to be easily and quickly
sized. The above limits certainly do vary as a funcon of esmated
operang hours, system operaons, pumping system and different
applicaons.

¹At low differential pressure the flow area required to achieve
higher flow exceeds the flow area available for the respective
Series. Therefore, the minimum pressure differential requirement
is increased for the higher flow ranges of some series Mesurflo
valves.
