For desulfurization wastewater containing lime sludge with a solid content of 4% and chloride ions at 20,000 ppm, what type of valve is suitable?
What type? ? Butterfly valve? ? Gate valve? ?
Can valves with a pressure rating of over 25 kg still be lined with rubber or plastic? ?
What specific operating conditions? Can cast iron, titanium alloy, and Hastelloy be used? I haven’t been in contact with it
Generally, rubber-lined disc valves are used, with the valve body lined with rubber and the valve disc made of an alloy
What is used for the valve seat and sealing surface? ? How to achieve wear resistance? ?
For this operating condition, the pump material can be one lined with ultra-high molecular weight polyethylene, which offers resistance to corrosion and wear. I think the valves should also be made of this material as well:victory:
321 is sufficient, thanks to low temperature and alkaline protection. Other ones such as rubber diaphragm valves are also fine.
