Gas Control Valve Calculator – Calculate Cg and Kg Coefficients
This Gas Control Valve Calculator helps you determine the capacity of a gas control valve based on given upstream and downstream pressures and a known flow coefficient (Cg or Kg). Whether you are selecting, sizing, or comparing gas control valves, this tool provides accurate calculations to optimize performance in industrial and commercial applications.
What is the Cg and Kg Flow Coefficient?
The flow coefficient (Cg or Kg) is a key parameter used to describe the flow capacity of a gas control valve. It represents the relationship between pressure drop (Δp) and flow rate (q), ensuring proper valve selection for efficient gas flow control. This calculator follows the EN 334 standard, which specifies requirements for gas control valves and pressure regulators for pressures up to 100 bar. The calculation method is based on turbulent flow conditions, applying the power law equation, where the Cg or Kg coefficient acts as a proportional constant.
