Selection of silicon powder medium valves
Thread Content
For selecting a valve to convey silicon powder, disc valves are expensive and not suitable for high pressures; which type of valve is more appropriate?
Let’s talk about the specific operating conditions – there’s a reason why expensive products are costly; those that are useful are generally expensive
Pressure is 22 kilograms; it is mainly used for the transportation of silicon powder
Personally, I think the key factor for valves is the hardness of the material; for ball valves, as long as the hardness can reach above HRC60, there should be no problem
22 kilograms is also a significant weight, so disc valves are the preferred choice. The 11th Aerospace Institute’s product is good – it requires no maintenance ； I’ve used other ones too; they get stuck after a year or two
One is wear-resistant, and the other is not prone to getting stuck
This seems to be quite consistent with the requirements for coal chemical industry pulverized coal ball valves
