For example a 1" Cv5.5 valve with a 3-8 range spring, if the cus-
tomer’s set point is P2 = 8 psi, then the actual Cv sizing should
not exceed 2.75Cv. If the customer’s intended set point is P2 =
5 psi, then the actual Cv sizing should not exceed 1.8Cv and if
their set point is P2 = 3 psi, then the actual Cv sizing should not
exceed 1.38 Cv.
