M-3
The listed Cv “factors” are derived from actual ow testing, in the Apollo® Ball Valve Division, Conbraco Industries, Inc., Pageland, South Carolina.
These tests were completed using standard “o the shelf” valves with no special preparation and utilizing standard schedule 40 pipe. It should
be understood that these factors are for the valve only and also include the connection conguration. The ow testing is done utilizing water
as a uid media and is a direct statement of the gallons of water owed per minute with a 1 psig pressure dierential across the valve/
connection unit. Line pressure is not a factor. Because the Cv is a factor, the formula can be used to estimate ow of most media for valve sizing.
