Summary

Flow coefficient, Cv, and Flow Factor, Kv, are values used to specify the hydraulic capacity of a control valve.

Flow coefficient is an imperial measurement and is defined as: the flow of water through a valve at 60°F in US gallons/minute (gpm) at a pressure drop of 1lb/in².

Flow factor is the metric equivalent of flow coefficient and is defined as: the flow of water in metres cubed per hour (m³/hr) at a pressure drop of bar.

This should not be confused with Discharge Coefficient which is a non-dimensional factor of a valve used to calculate flow that discharges to the environment.

Convert Flow Coefficient to Flow Factor

Convert flow coefficient in US gpm.psi to flow factor in (m³/hr).bar:
Formula:
	Cv = flow coefficient
Cv
Result:	(m³/hr).bar

Convert Flow Factor to Flow Coefficient

Convert flow factor in (m³/hr).bar to flow coefficient in US gpm.psi:
Formula:
	Cv = flow coefficient
Cv
Result:	US gpm.psi
