Upgrading of valves in the fractionated slurry system: Are there new materials or improved coating wear-resistant technologies for these valves?
Here, the basic filters we use are equipped with dual valves; replacing them once per cycle is not a problem, and it’s sufficient to keep the solid content in the slurry under control. Additionally, valves made of new materials are relatively expensive, usually costing more than twice as much as ordinary valves. Given the unknown safety aspects, it is more reasonable to use two valves!
What you say isn’t entirely accurate; under normal circumstances, it’s okay to say that! If the purpose is to regulate the flow rate, the first valve should be fully open while the second valve should be closed. The first one provides protection for the second valve.
We still use alloy steel valves; they haven’t been replaced in a long time. The preheating valve of the slurry pump is that valve which needs to be replaced during each maintenance session due to wear and obstruction
