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

The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: WebJul 19, 2024 · To calculate the rate of flow, you need to know the volume (V) and the time (t) it takes for that volume to pass through the valve.
