Q:CV PRESSURE DROP FORMULA

The flow coefficient (Cv) and its metric equivalent (Kv) are essential parameters that define the flow performance and pressure characteristics of a valve. These values are calculated according to the ISA–S75.01–1985 standard for turbulent flow conditions. Cv represents the flow rate of water, in U.S. gallons per minute, that passes through a valve with a pressure drop of 1 psi, while Kv expresses the same performance in cubic meters per hour under a pressure drop of 1 bar.
Understanding these values allows engineers to accurately determine valve sizing, predict flow behavior, and optimize system performance. Dual plate check valves with properly selected Cv and Kv values ensure stable operation, minimized pressure loss, and enhanced energy efficiency across water treatment, HVAC, marine, and industrial pipeline systems.
