Phosphoric acid – Recommended valves :

Industrial phosphoric acid solutions are very aggressive due to impurities coming from natural phosphate rocks. Pumps and valves must be made of corrosion resistant alloys such as super-austenitic stainless steel (AISI 904L or Uranus B6, Hastelloy, Incoloy, Inconel) or high chromium content.
