PN16 Y Type Bellow Seal Globe Valve (Manual, Flange & Butt Welded)<\/h1>\n

I. Product Overview<\/h2>\n
VALVEFAC PN16 Y type bellow seal globe valve is a versatile flow control solution engineered for industrial pipelines, featuring manual operation and dual connection options (flange, butt welded). Crafted with WCB, stainless steel, and forged steel, it combines a Y-type flow path with a bellow seal structure to balance precise regulation and zero leakage. Operating at -20\u2103~425\u2103, it leverages a stainless steel bellow to eliminate stem leakage\u2014critical for media like water, steam, and light oil. Compliant with international standards, it is ideal for general industrial systems, heating circuits, and medium-pressure pipelines, where reliable sealing and flexible installation are key.<\/div>\n

II. Key Attribute Parameters<\/h2>\n
    \n
  • Size Range<\/strong>: Covering common industrial diameters (e.g., DN80), adaptable to small to medium pipelines.<\/li>\n
  • Pressure Rating<\/strong>: PN16 (1.6MPa), suitable for low to medium-pressure systems such as heating networks and auxiliary steam lines.<\/li>\n
  • Temperature Range<\/strong>: -20\u2103~425\u2103, with WCB\/stainless steel retaining stability in high-temperature media like steam.<\/li>\n
  • Material Configuration<\/strong>:\n
      \n
    • Body<\/strong>: WCB (cost-effective), stainless steel (corrosion resistance), or forged steel (enhanced strength).<\/li>\n
    • Bellow<\/strong>: Stainless steel, forming a hermetic barrier between stem and media to prevent leakage.<\/li>\n
    • Seal<\/strong>: Stainless steel or Stellite (wear-resistant), ensuring tight shut-off under frequent operation.<\/li>\n
    • Stem<\/strong>: Stainless steel, isolated from media by the bellow to avoid corrosion and ensure smooth movement.<\/li>\n<\/ul>\n<\/li>\n
    • Connection Types<\/strong>: Flange (for easy disassembly) and butt welded (for leak-tight, permanent installation).<\/li>\n
    • Actuation<\/strong>: Manual (handwheel), with intuitive operation for precise flow adjustment.<\/li>\n
    • Design Standards<\/strong>: Complies with industrial norms for dimensions and performance, ensuring compatibility with global pipelines.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
