Suitability of materials of Air release valves for sulphuric acid
Suitability of materials of Air release valves for sulphuric acid
(OP)
Hi all,
i'm faced with a problem of finding a suitable air release valve for a chemical dosing line (sulphuric acid at 98% concentration). I have looked at SS 316 valves, PVDF valves and wondering if there is hastelloy valves as it is superior in chemical resistance to H2SO4 at 98%. Having said that, none of the valve vendors are interseted in offering a valve that is suitable.
Having a look on google, there arent much avilable either.
just wondering if anyone here have had experience with H2SO4 and air release valves?
