The CRYOGENIC GATE VALVE TYPE 01311 is engineered for superior performance in extreme low-temperature environments, making it an essential component in industries such as LNG processing, aerospace, and medical gas systems. Featuring an extended spindle and a throughthing pole with brazed copper ends, this valve ensures reliable operation, minimal heat transfer, and enhanced durability under cryogenic conditions. Its design prioritizes safety and efficiency, providing leak-tight sealing and smooth actuation to maintain system integrity.Constructed with high-quality materials and precision manufacturing, this gate valve offers exceptional resistance to thermal contraction and mechanical stress. The extended spindle allows for easy installation and operation in hard-to-reach areas, while the brazed copper ends ensure a secure, robust connection compatible with cryogenic piping systems. Key features include:Extended spindle for accessible operation in confined spacesThroughthing pole design for consistent performance and stabilityBrazed copper ends for leak-proof connections and corrosion resistanceOptimal for temperatures as low as -196°C (-320°F)Complies with international standards for cryogenic applicationsIdeal for use in liquefied natural gas (LNG) plants, industrial gas storage, and cryogenic research facilities, this valve supports critical processes with high reliability and low maintenance requirements. Its robust construction and specialized design make it a preferred choice for engineers and technicians seeking to enhance system safety and operational efficiency in challenging environments.
