Valve Cv Calculator For Air. The flow of water through a valve at 60°f in us gallons/minute (gpm) at a pressure drop of 1lb/in². Go to online calculation of the flow coefficient cv and kv.
It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. In deciding the size of the control valve that (port size) we need to calculate the cv value of the process (calculated cv) by calculating cv has educated more than 50 years, which is involved in.
