The “valve flow coefficient” is abbreviated as Cv.
Significance of Cv:
- Cv indicates the volume of fluid that can pass through a valve when it is fully open.
- The capacity of a control valve to flow fluid is measured by the control valve flow coefficient (Cv).
- It is employed to figure out the flow rate via the valve under specific operational circumstances.
- It is used to compare the flow rates of several valves and choose the right size valve for a particular application.
- Comparatively to a valve with a lower Cv rating, a higher Cv rating valve can manage a larger flow rate. As a result, the fluid flow via the valve may be precisely controlled, ensuring that the system works as it should.
- Control valves are employed in numerous industrial processes, including those that process oil and gas, food and beverages, and chemicals.
- Cv values aid in the selection and sizing of control valves.
