I would appreciate some guidance: what is the physical meaning of the CV parameter of a self-control regulating valve?
The Cv value is an important parameter for control valves; it reflects the capacity of the valve. The nominal diameter of the control valve is determined based on the value of Cv. The Cv value is defined as the number of US gallons per minute of clean water at 60°F (15.6°C) that pass through the valve, with the valve in its fully open position and a pressure difference of 1 pound per square inch across it. China’s flow coefficient is defined according to the metric system. The symbol is Kv, and the relationship between Kv and Cv is Cv=1.17Kv.
Take a look at reply 2#; I also learned a few things from it
Cv is the flow coefficient of control valves in non-SI units; it represents the number of US gallons of water at a pressure drop of 1 psi that pass through in 1 minute, at temperatures ranging from 40°F to 100°F (4°C to 38°C)
