You can calculate the gas control valve capacity for given upstream and downstream pressure
and known flow coefficient Cg or Kg.
Standard EN334 is covering gas control valves and pressure regulators for pressures up to
100 bar. The calculator is in line with the same standard.
The calculator is calculating flow coefficient Cg or Kg using the relationship between
pressure drop and flow rate in the control valve which is for complete turbulent flow
following power law where flow coefficient is the proportional constant.
