The listed Cv “factors” are derived from actual flow testing, at Apollo’s Pageland, South Carolina factory. 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 configuration. The flow testing is done utilizing water as a fluid media and is a direct statement of the gallons of
water flowed per minute with a 1 psig pressure dierential across the valve/connection unit. Line pressure is not a factor. Because the C
formula can be used to estimate flow of most media for valve sizing.
