kv/cv-Value Calculator

The valves flow coefficient value (kv/cv) for the desired flow rate is calculated. The valve to be selected should provide a kvs/cvs value which is approximately 30% higher than the calculated kv/cv value (=smallest kvs/cvs value). Both values are shown under “Results”. The selected valve should meet the calculated kvs/cvs. Please note that the flow coefficient values stated in our specifications and data sheets always represent the kvs value in [m³/h].
