Check valve cv values. Cv value opening degree 0 10 20 30 40 50 60 70 80 90 100 0 50 100. The valve flow coefficient cv is the number of u s. The valve flow coefficient cv or its metric equivalent kv has been adopted universally as a comparative value for measuring the capacity of control valves.

Kv 0 864 cv at a particular percentage of opening of valve giving cv 1 will pass 1us gpm at 60 f and a pressure differential of 1 psi upstream and downstream across the valve. Gallons per minute of water at 60 f that will flow through a control valve at a specified opening when a pressure differential of 1psi. C v calculator for valve sizing.

Cv value opening degree 0 10 20 30 40 50 60 70 80 90 100 0 50 100. The 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. Such as the renault number reynolds number flow rate flow the shock choking the involved joints in pipes fitting and the other by the values of these.

Cv value for each opening degree. In deciding the size of the control valve that port size we need to calculate the cv value of the process calculated cv by calculating cv has educated more than 50 years which is involved in.
