Description

The CRYOGENIC CHECK VALVE TYPE 05418 is engineered for superior performance in extreme low-temperature applications, ensuring reliable unidirectional flow control in industrial cryogenic systems. Constructed with high-grade materials resistant to thermal contraction and embrittlement, this valve maintains integrity and functionality at temperatures as low as -196°C. Its design adheres to DIN standards with PN40 pressure rating flanges, providing a secure, leak-proof connection suitable for high-pressure environments commonly found in LNG, industrial gas, and chemical processing plants.Key features of this cryogenic check valve include:Robust construction with stainless steel or cryogenic-grade alloys for durability and corrosion resistanceSpring-assisted closing mechanism to prevent backflow and ensure swift, positive sealingCompliance with international standards including DIN and PN40 for flange connectionsOptimized for use in liquid nitrogen, oxygen, argon, and other cryogenic fluidsMinimal pressure drop design to enhance system efficiency and reduce energy consumptionIdeal for applications in aerospace, medical gas systems, and energy sectors, this valve offers exceptional reliability and safety. Its precision engineering minimizes maintenance requirements and extends service life, making it a cost-effective solution for critical cryogenic infrastructure. Easy installation and compatibility with standard DIN PN40 flanges ensure seamless integration into existing systems, supporting operational continuity and performance excellence.
