Performance Data
Table shows flows (gpm – water) at various pressure drops (psi)
using standard screens.
Flow-coefficient
The flow coefficient (Cv) is the number of gallons per minute of
water flowing through a given size restriction at a pressure drop of
one psi. To obtain the Cv factor for a given size strainer, read
capacity at intersection with the one (1) psi pressure drop.
