Pressure Loss and Flow Resistance Coefficient of Pneumatic Butterfly Valves

The flow resistance coefficient of the pneumatic butterfly valve refers to the loss of fluid resistance when the fluid passes through the valve, which is represented by the fluid pressure drop △p before and after the valve.

Fluid resistance of butterfly valve: The flow resistance coefficient of the valve depends on the size, structure and shape of the inner cavity of the valve product. In order to reflect the influence of the valve on the fluid resistance, the resistance data of some common valve elements are quoted, which reflect the relationship between the shape and size of the valve element and the fluid resistance.
