Are valves made of zirconium generally resistant to methyl acetate?

Zirconium possesses a range of excellent properties, including high temperature resistance, good corrosion resistance, machinability, favorable performance, and a low thermal neutron absorption cross-section. It is therefore an important structural material for nuclear reactors. Zirconium and its alloys are unique in terms of their corrosion resistance in alkali solutions of various concentrations as well as in molten alkalis; their performance is even better than that of tantalum. The series of zirconium-based valves developed in China are widely used in the chlor-alkali industry, soda ash industry, pharmaceutical industry, fertilizer industry, fine chemical industry, textile fiber synthesis and dyeing industries, as well as in the production of basic organic acids and inorganic salts, and in the nitric acid industry. Zirconium is mainly used in equipment with high requirements for corrosion resistance, such as in the manufacture of reactors, acid- and heat-resistant pumps, heat exchangers, dip tanks, exhaust impellers, valves, agitators, nozzles, thermocouple sleeves, conduits, container linings, and environmental protection equipment. Zirconium is used in many chemical processing equipment and key components for producing fertilizers, resins, plastics, and acids. It is said that valves made of zirconium material are generally resistant to methyl acetate
If the temperature isn’t high, a lined valve should suffice
If the corrosive medium also contains crystals and particles, what materials should be used for pipes and valves? Please help with an answer, thanks!
Zirconium is corroded by hydrofluoric acid, concentrated sulfuric acid, and phosphoric acid at certain concentrations and temperatures
