Analysis of Imbalanced Fluid Force Inside a Cage-type, Low Noise, Control Valve

摘要

Relatively large, imbalanced fluid forces occur inside of a cage-type, low noise, control valve when used under severe conditions such as with large valve sizes and high direct or differential pressures. Analysis of the fluid force for such valve applications is therefore very important. The mechanism was analyzed, and a useful formula to calculate the imbalanced fluid force was derived.
