For black water corner valves, is better linear regulation or equal percentage regulation?

Thread Content

I have a question for the more experienced colleagues: Regarding the angle valve used in gasification black water systems, the fluid flowing through this valve is hot water containing a certain amount of sludge; it is a mixture of water and sludge. Moreover, there is a significant pressure difference before and after the valve, which causes flashing of the black water at the valve site, resulting in considerable wear on the valve. Gases such as H2, CO, CO2, H2S, and NH3 are dissolved in the medium, giving it certain corrosive properties. In many cases, the valve internals need to have a reduced diameter, and the valve experiences significant vibration at low opening degrees. When the diameter is small, there’s a risk of it getting clogged by ash or other debris; on the other hand, if a larger diameter is chosen, there’s a concern that the opening will be too small. It’s a difficult dilemma. Is it better to choose linear for valve characteristics?
