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. To find Q, divide V by t. So if we … WebThe formula below allows for calculation of flow rate and pressure drop through a valve with a specified Cv value. During the process of valve size selection, the same formula is used determine the valve Cv necessary for a required flow rate and desired pressure drop. Butterfly valve Cv values vary with the disc angle and valve size.

WebFeb 21, 2024 · C = Q/N1 * √ (ρ1/ρ0) / (∆P) C is the Flow Coefficient which describes how much fluid will flow through the valve for a given pressure drop. Q is the Flow Rate (m3/h, GPM, SCFH). ∆P is the differential pressure between upstream and downstream pressure taps (kPa, bar, psi). ρ1/ρ0 is the relative density. WebCV Calculator / Regulator Flow Curve. 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.

WebThe valve flow coefficient (C v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters. The C v calculator will calculate either C v or flow using the supplied additional parameters of fluid, inlet and outlet pressure, … WebThis is our valve Cv calculator. It allows you to calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure …

WebFlow is proportional to the value of Cv. For example, a Cv of 150 would then equate to 150 gpm of water at 60' F with a differential pressure of one psi. The formula below allows for …
