What kind of valve is suitable for dilute sulfuric acid with particles?
Thread Content
The ball valve made of 316L corroded after just a few months of use. What material is best for valves that are resistant to wear and corrosion? :o
316L cannot be used. Depending on how dilute the sulfuric acid is and what the solid-liquid ratio is, a rubber hose valve should be used when there are many solid particles, while a diaphragm valve lined with PTFE should be used when the solid-liquid ratio is low
Same as above; a PTFE diaphragm valve is recommended
For better wear resistance, use F4-lined ball valves; as for corrosion resistance, there’s no need to say more – they can withstand temperatures of 150 degrees
We recommend the PTFE diaphragm valve! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
