Definition of Cryogenic Needle Valve

A cryogenic needle valve is a professional ultra-low temperature resistant needle valve specially designed for ultra-low temperature liquefied gas fluid control scenarios. It is suitable for conveying a variety of high-risk cryogenic media, including LO2 (liquid oxygen), LN2 (liquid nitrogen), LAr (liquid argon), LNG (liquefied natural gas), LC2H4 (liquid ethylene), ethylene, liquid hydrogen, liquid ammonia, liquid propane and liquefied petroleum gas.

Imported cryogenic needle instrument valves adopt the same structural form as standard globe valves, and are equipped with a specialized extended stem design, which can stably withstand ultra-low temperature down to -196℃, ensuring normal operation and reliable sealing in extreme low temperature environments without performance failure.

Technical Parameters of Cryogenic Needle Valve

Product Characteristics of Cryogenic Needle Valve

• Ultra-Low Temperature Adaptability: The selected special stainless steel metal materials can stably maintain all required mechanical properties under extreme ultra-low temperature conditions down to -196℃, ensuring normal opening, closing and regulation functions.

• Excellent Low-Temperature Toughness: Possesses outstanding impact toughness, qualified relative elongation and high structural stability, avoiding material brittle fracture failure in ultra-low temperature environments.

• Low-Temperature Wear Resistance: Features excellent wear resistance even under ultra-low temperature and oil-free lubrication working conditions, reducing component wear and extending service life.

• Strong Corrosion Resistance: Made of professional austenitic stainless steel materials, with good corrosion resistance, adapting to the corrosion characteristics of various cryogenic liquefied gases.

• Good Weldability: For models adopting welded connection, the selected valve body materials have excellent weldability, ensuring firm and reliable welding and no leakage risk in ultra-low temperature environments.
