Operating parameters: 20 bar of steam before the valve, 10 bar of steam after the valve; normal steam flow rate is 27 t/h, steam density is 0.8, and the temperature ranges from 195 to 220 degrees. Question: What diameter should be chosen? What is the CV value? What type of valve should be used?
Go and ask those manufacturers of valve systems for power plants; they are very professional
DN250: CV value of 380 selected; calculated CV value is 139.995. The selection is based on this CV value; at an opening of 27 T/h, the percentage is 74.47%. Sleeve valve, material: WCB/316+ST/316+ST; extended valve cover; graphite packing
A sleeve control valve with two-stage noise reduction is sufficient; a DN200 diameter is appropriate. The following are the results obtained using the company’s selection software
Heating companies – they’re the best at this

Up to 220 degrees – it’s not considered a high-temperature valve. Why use a valve cover with radiators when a regular one will do just fine?

Any valve supplier can provide you with these parameters; for steam applications, it’s best to use sleeve valves with a heat-dissipating type of valve cover
For standard cage structures–if there is noise, one or multiple levels of noise reduction are available; detailed technical support can be provided
