Zirkonium-R\u00fcckschlagventil<\/h2>\n

WDL Zirconium Check Valve<\/strong> provides automatic prevention of reverse flow for process systems that need resistance to many strong acids and corrosive chemical mixtures. Zirconium is used for severe acid duties where stainless steels and many nickel alloys cannot provide an acceptable corrosion rate.<\/p>\n<\/section>\n

    H\u00e4ufig gestellte Fragen<\/h2>\n

    Why select Zirconium for this check valve?<\/h3>\n

    Zirconium is used for severe acid duties where stainless steels and many nickel alloys cannot provide an acceptable corrosion rate. Final suitability depends on the complete process conditions and the selected valve trim.<\/p>\n
