DA22Y-40P DN10/15 Stainless Steel Cryogenic Relief Valve – Hard Seal Type for -196°C

5 0 Reviews

This safety valve features a durable metal-to-metal (hard seal) seat structure, ideal for cryogenic gas systems such as LNG, LN2, LOX, and LAr. It offers stable pressure relief at ultra-low temperatures down to -196°C, ensuring long service life and leak-free performance in extreme environments. The valve body is made of stainless steel or brass and is CE & ISO certified. Widely used in cryogenic tanks, pipelines, and industrial gas applications. Available in multiple pressure ranges, sizes, and connection types.

Hard Seal Cryogenic Safety Relief Valve – Built for Extreme Conditions
Our hard-seal cryogenic safety relief valve is specially designed for low-temperature applications requiring high durability and zero leakage. The valve features a metal-to-metal sealing structure, which provides enhanced resistance to wear, deformation, and cryogenic shock. It performs reliably under -196°C and is ideal for liquefied gas systems such as LNG (Liquefied Natural Gas), LN₂ (Liquid Nitrogen), LOX (Liquid Oxygen), and LAr (Liquid Argon).

The valve is manufactured using high-quality stainless steel or brass, tested under strict CE and ISO standards. It is suitable for overpressure protection in cryogenic tanks, pipelines, ISO containers, vaporizers, and industrial gas plants. Customizable pressure settings, ports (threaded or flanged), and OEM branding are available.
