The CRYOGENIC GATE VALVE TYPE 02411 WITH EXTENDED SPINDLE ON FLANGE CONNECTION is engineered for superior performance in extreme low-temperature applications. Constructed with precision and durability in mind, this valve ensures reliable shut-off and control in cryogenic systems, making it an essential component for industries such as LNG processing, industrial gas production, and aerospace. Its extended spindle design allows for safe operation by maintaining a distance between the operator and the cryogenic fluid, reducing the risk of cold burns and enhancing operational safety.This gate valve features a robust flange connection that guarantees a secure and leak-proof seal, critical for maintaining system integrity under high-pressure and ultra-low temperature conditions. The valve body is manufactured from high-grade materials capable of withstanding thermal contraction and resisting brittleness, ensuring long service life and minimal maintenance. Its gate mechanism provides a tight seal with low torque operation, facilitating easy opening and closing even in the most demanding environments.Key specifications and benefits include:Designed for temperatures as low as -196°C (-320°F)Flange connection complies with international standards (ANSI, DIN, etc.)Extended spindle for operator safety and ease of accessBubble-tight shut-off to prevent leakageSuitable for oxygen service with proper cleaning protocolsAvailable in various sizes and pressure ratings to meet specific application requirementsIdeal for use in cryogenic storage tanks, transportation vessels, and processing plants, the Type 02411 valve is a trusted solution for managing the flow of liquefied natural gas (LNG), liquid nitrogen, oxygen, argon, and other cryogenic fluids. Its design prioritizes safety, efficiency, and reliability, making it a top choice for engineers and procurement specialists in the cryogenics industry.
