The CRYOGENIC GATE VALVE TYPE 01311 is engineered for superior performance in extreme low-temperature environments, making it an essential component for industries such as LNG processing, aerospace, and medical gas systems. Featuring an extended spindle and brazed stainless steel ends, this valve ensures reliable operation, minimal heat transfer, and exceptional durability under cryogenic conditions down to -196°C. Its design prioritizes safety and efficiency, providing leak-proof sealing and easy maintenance, which reduces downtime and operational costs.Constructed with high-quality stainless steel, the valve body resists corrosion and thermal shock, while the extended spindle allows for safe operation by keeping the handwheel at a manageable distance from the cold source. The brazed ends offer a robust, permanent connection that enhances structural integrity and prevents leaks, ideal for critical applications where failure is not an option. This valve is tested rigorously to meet international standards, ensuring compliance and reliability in demanding industrial settings.Key features include:Extended spindle for operator safety and accessibilityBrazed stainless steel ends for leak-proof performanceDesigned for cryogenic applications down to -196°CCorrosion-resistant stainless steel constructionComplies with industry standards for quality and safety
