Control Valve Sizing Calculator

A control valve sizing calculator finds the flow coefficient (Cv or Kv) a valve needs to pass the required flow at the available pressure drop, then checks for choked flow, cavitation, flashing, noise and velocity. This free calculator applies IEC 60534-2-1 for liquid, gas and steam service and reports the expected valve opening on the … Read more
