Question: Valve selection regarding pipes containing metal, iron slag, and nails
Thread Content
I would like to ask the experts: for valves dealing with media in pipes that contain metal particles, iron slag, and nails, which type of valve is suitable? Apart from knife gate valves, are there any better valve options available besides V-ball valves (the performance of knife gate valves and V-ball valves is not ideal)?
Let’s learn about it together*; I want to know what medium it is What are the pressure, temperature, and flow rate of the medium?
Lever-type wear-resistant hemispherical valve; feel free to contact me
What are the requirements for the level of leakage? Could you describe it in more detail?

Personally, I think it’s not a problem with the valve’s structure but rather with its material. The reason it can’t be used is that there are many particles and iron residues, which cause damage to the valve. Therefore, I believe it might be necessary to change the material of the valve (for example, to ceramics, silicon nitride, or silicon carbide)
Why not remove it? Add an iron removal device. Otherwise, it’s impossible to measure the traffic
I want to know the leakage level and whether it is high voltage; otherwise, it’s difficult to provide valid results. Can’t C either? I think if it’s not corrosive and the leakage level requirements aren’t high, it’s a bit easier to handle. I assume that there is no corrosion under operating conditions, but the leakage requirements are very high; in that case, a gate valve would still be the appropriate choice. The sealing surfaces should be made of rubber, and the gate plate should also be covered with a layer of rubber to prevent wear or the accumulation of metal in the grooves, which could damage the sealing surfaces. Additionally, holes can be drilled in the valve body and plugs installed to allow for regular cleaning of any deposits – this should solve the problem
What you’re referring to isn’t rubber lining. The medium is not very corrosive. The pressure isn’t very high either. The main requirement is regarding the level of leakage.
The magnetizer can’t be used because it’s impossible to stop the vehicle.
