II. Key Attribute Parameters

• Size Range: 1/2″~10″ (DN15~DN250), covering small to medium-diameter pipelines. From 1/2″ laboratory liquid hydrogen lines to 10″ industrial LNG transmission pipes, it adapts to diverse cryogenic flow control needs.
• Pressure Rating: 150LB~600LB (PN16~PN100). 150LB suits low-pressure cryogenic storage; 600LB handles high-pressure systems like natural gas vaporization lines, ensuring stability under varying pressure conditions.
• Temperature Range: -196℃~450℃. F304L/F316L retains impact toughness at ultra-low temperatures (avoiding brittleness) and resists oxidation at high temperatures, covering extreme cryogenic to medium-high temperature working conditions.
• Material Configuration:
  • Body, Ball & Stem: Forged F304L (low-carbon 304) or F316L (low-carbon 316) stainless steel. F304L minimizes intergranular corrosion; F316L adds molybdenum for enhanced chloride resistance—both maintain ductility at -196℃, critical for cryogenic safety.
  • Seat: RPTFE (15% glass fiber filled) for -196℃~180℃ or PEEK for up to 260℃. These materials resist cold flow (deformation under low-temperature pressure) and ensure reliable sealing.
• Connection Type: Butt welding, creating a seamless, leak-tight joint. Welded ends eliminate flange/gasket leakage points, withstanding thermal expansion and vibration in high-integrity cryogenic pipelines.
• Actuation: Manual (handwheel) with optional worm gear/pneumatic actuators. Handwheels feature ergonomic design for easy operation even with cold-protection gloves.
• Design & Test Standards: Follows API 6D, API 608; testing complies with API 598 (hydrostatic test at 1.5×rated pressure) and API 607 (fire safety test) to ensure performance and safety.
