Brochure

The following formula can be used by referencing the following flow table and product graph..
Q
= Flow rate (GPM)
Ps = Differential pressure (signal) through the test points of the valve (psi)
Cvs = Flow coefficient through the test points of the valve (GPM/psi )
Q
= Flow Rate (GPM)
P = Differential pressure (pressure loss) across the valve (psi)
Cv = Flow through valve (GPM @ 1psi pressure drop )
