Selection of control valves for gases containing large amounts of dust
Thread Content
A large amount of dust in the fluid causes severe wear on control valves. There was once a butterfly valve that, due to not being closed properly, became worn through and started leaking in a short time. For gases containing large amounts of dust, only on-off valves can be used; are there no good control valves available? The resistance of globe valves is too high
Dust causes significant impact wear on control valves; in particular, the valve core and seat areas require special treatment, such as welding special metals onto them! What do you think of an eccentric rotary valve?
The sealing surface of a ball valve is linear, and it can be easily worn by debris, leading to leaks; perhaps plug valves would work better, as their sealing mechanism involves surface contact
I’m not sure what role this valve plays in the manufacturing process? If no adjustment is needed and a two-position system is sufficient, I recommend using ball valves, such as those used in our company’s automatic catalyst feeding system.
