Brief: Discover the Cryogenic 3-Piece Welded Ball Valve, designed for low-temperature service down to -320°F (-196°C). Perfect for LNG, liquid nitrogen, and oxygen handling, this valve features an extended bonnet, low-temperature seat materials, and leak-tight welded construction for reliable performance in extreme cold.
Related Product Features:
  • Extended bonnet (stem extension) separates the operating mechanism from cold fluid, preventing stem seal freeze.
  • Low-temperature seat materials like glass-filled PTFE or modified PEEK remain flexible at cryogenic temperatures.
  • Deep cryogenic treatment ensures dimensional stability and material integrity.
  • Leak-tight welded construction with butt-weld ends provides superior sealing compared to flanged or threaded connections.
  • Operates safely from -320°F to 180°F (-196°C to 82°C).
  • Made from 304L or 316L stainless steel for improved toughness.
  • Compliant with BS 6364 for cryogenic service valves.
  • Ideal for LNG terminals, industrial gas production, and aerospace test facilities.
Las preguntas:
  • What temperature range can the Cryogenic 3-Piece Welded Ball Valve handle?
    The valve operates safely from -320°F to 180°F (-196°C to 82°C), making it suitable for extreme low-temperature applications.
  • What materials are used for the valve body and seats?
    The valve body is made from 304L or 316L stainless steel, while the seats use glass-filled RPTFE, PEEK, or VESPEL® for extreme conditions.
  • Why is an extended bonnet important in cryogenic valves?
    The extended bonnet (stem extension) separates the standard operating mechanism from the cold fluid, preventing stem seal freeze and ensuring operability in low-temperature environments.
