Swagelok Hamburg Services Online Tools CV Calculator

Use caution when applying these results to a pressure regulator. The Cv of a regulator represents its FULLY OPEN flow capacity, while a regulator is never intended to be used at that point. Multiply the results by 1.5 for a margin of safety and consult the product's flow curves in the product literature.
