Please ask an expert to help calculate the size of the control valve.

Our company needs to purchase a self-acting control valve of the ZZYP-16 (B) type. The medium flowing through it is gaseous CO2, with a density of 1.977 kg/m3. The flow rate is 1000 Nm3/h, the inlet pressure ranges from 1.6 to 2.3 Mpa, the outlet pressure ranges from 0.7 to 1.5 Mpa, and the operating temperature ranges from -19 to 40 degrees Celsius. We would appreciate it if experts could help us calculate the appropriate size for this valve. Thank you!
Or is it possible to calculate the value of KV?
I wonder what the temperature of your CO2 is? Only then can we calculate it!! QQ: 928976489
Sure, you can find someone from the design institute and entrust the task to them.
The temperature of CO2 is between -19 and 40 degrees; please consider the maximum value obtained.
A 1'' pipe is considered a 1-inch valve; it’s best to have a noise reducer installed. What is the diameter of your pipes at 300 lb ps? If they are 2'' pipes, the noise level is relatively low, around 80.
The maximum Cg value is 484； For self-acting control valves, a DN25 valve will suffice; the noise level is 86.8 ； For valves, it is recommended to use DN40 or DN50 models, as this will eliminate noise issues.
