💡Kv is the flow of water in m³/h at 1 bar pressure drop across the valve. Cv is the US equivalent in US gallons per minute at 1 psi drop. The pneumatic qn value refers to normal-litres per minute of air at specified conditions. Always verify units with the manufacturer's datasheet.

Kv = Cv × 0.865 | kv [l/min] = Cv × 14.3 | qn [nl/min] = Cv × 981.5
