How to calculate mass flow rate through valve for non-choked flow?

WebValve Flow Coefficient (Cv) is a valve’s capacity for a liquid or gas to flow through it. It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop … WebAlthough all valves have the same basic components and function to control flow in some fashion, the method of controlling the flow can vary dramatically. In general, there are four methods of controlling flow through a valve. Move a disc, or plug into or against an orifice (for example, globe or needle type valve).
