1\/2\u2033~24\u2033 DIN API Bellow Sealed Globe Valve for Toxic Liquid & Industrial Use<\/h1>\n

I. Product Overview<\/h2>\n
VALVEFAC bellow sealed globe valve is a specialized flow control solution engineered for handling toxic gases, hazardous liquids, and common industrial media. Crafted with GS-C25 cast steel and stainless steel (CF8, CF8M), it features a metal bellow seal structure and flange connection to ensure zero leakage. Operating at -29\u2103~500\u2103 and 150LB~2500LB (PN6~PN160) pressure, it replaces traditional packing seals with a stainless steel bellow, forming a hermetic barrier between the stem and media. Compliant with DIN, API, and ASME standards, it is ideal for chemical, petroleum, and industrial systems where leakage of toxic or hazardous media could pose safety or environmental risks.<\/div>\n

II. Key Attribute Parameters<\/h2>\n
    \n
  • Size Range<\/strong>: 1\/2\u2033~24\u2033 (DN15~DN600), covering small to large-diameter pipelines for toxic liquid transfer, steam systems, and hazardous media control.<\/li>\n
  • Pressure Range<\/strong>: 150LB~2500LB (PN6~PN160), adapting to low to ultra-high pressure systems such as chemical reaction pipelines and high-pressure gas lines.<\/li>\n
  • Temperature Range<\/strong>: -29\u2103~500\u2103, with material options (e.g., WC6 for high temp) retaining stability in extreme thermal conditions\u2014critical for steam and hot oil applications.<\/li>\n
  • Material Configuration<\/strong>:\n
      \n
    • Body & Bonnet<\/strong>: GS-C25 (general use), CF8\/CF8M (corrosion resistance for toxic media), WC6 (high-temperature strength for steam).<\/li>\n
    • Bellow<\/strong>: Stainless steel 321\/316, welded to the stem and bonnet to prevent leakage; 316 offers superior resistance to corrosive toxic liquids.<\/li>\n
    • Disc & Seat<\/strong>: WCB+13Cr or Stellite, with cone-shaped disc design for tight sealing and wear resistance in frequent operation.<\/li>\n
    • Stem<\/strong>: Stainless steel 304\/316, isolated from media by the bellow to avoid corrosion and ensure smooth movement.<\/li>\n
    • End Connections<\/strong>: Flanged (per ASME B16.5\/DIN 2543), enabling secure integration with industrial pipelines.<\/li>\n<\/ul>\n<\/li>\n
    • Actuation<\/strong>: Manual (handwheel), with ergonomic design for easy operation even in high-pressure scenarios.<\/li>\n
    • Design & Test Standards<\/strong>: Design follows API 6D, DIN 3356; testing complies with API 598, including hydrostatic and air tightness tests to ensure zero leakage.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
