Doppelsitz-Kugelhahn<\/h2>\n

WDL-Duplex-Kugelhahn<\/strong> provides quarter-turn isolation with a direct flow path and tight shutoff for process systems that need high strength with resistance to chloride pitting and stress-corrosion cracking. Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel.<\/p>\n<\/section>\n

    Hinweise zur Auswahl<\/h2>\n

    Choose 2205, 2507 or another grade from chloride level, temperature, pressure and required pitting resistance.<\/p>\n

    Bitte best\u00e4tigen Sie die Ausf\u00fchrung (schwimmend oder mit Drehzapfen), die Hohlraumentlastung, das Sitzmaterial, die Anforderungen an die Feuerbest\u00e4ndigkeit und den Bohrungsdurchmesser.<\/p>\n<\/section>\n

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

    Why select Duplex Stainless Steel for this ball valve?<\/h3>\n

    Duplex stainless steel combines austenitic and ferritic phases for chloride service that requires higher strength than 300-series stainless steel. Final suitability depends on the complete process conditions and the selected valve trim.<\/p>\n

    Welche Informationen werden f\u00fcr die Auswahl ben\u00f6tigt?<\/h3>\n

    Geben Sie die Gr\u00f6\u00dfe, die Druckstufe, die Zusammensetzung des Mediums, die Konzentration, die Temperatur, die Anschlussnorm, die Betriebsart und die ben\u00f6tigte Menge an.<\/p>\n<\/section>\n
