Control Valve Cv Calculator (IEC 60534 / ISA S75.01)
Sizing a control valve correctly is one of the most critical steps in process engineering. If a valve is undersized, it won’t be able to pass the required flow. If it is oversized, it will operate too close to its seat, leading to poor control, instability, and premature wear. This interactive tool calculates the required Flow Coefficient ($C_v$) for both liquid and compressible gas/vapor services based on the international standard IEC 60534-2-1 (equivalent to ISA S75.01). ...
