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 braze copper ends, this valve ensures reliable operation and leak-tight sealing where thermal contraction and operational safety are critical. Its robust construction complies with international standards, providing durability and efficiency in cryogenic applications down to -196°C.Key features include:Extended spindle design for easy access and operation in insulated linesBraze copper ends for secure, high-integrity connections resistant to thermal cyclingFull bore design to minimize pressure drop and allow for pigging or cleaningStainless steel body for corrosion resistance and longevity in harsh conditionsBubble-tight sealing with resilient seats to prevent leakage under cryogenic temperaturesIdeal for use in liquid nitrogen, oxygen, argon, and other cryogenic fluid systems, this gate valve offers exceptional shut-off capabilities and is designed for manual or automated actuation. Its extended spindle allows for installation in deep insulation layers, reducing heat ingress and maintaining system efficiency. Trusted by engineers and procurement specialists worldwide, the Type 01311 valve enhances operational reliability and safety in critical cryogenic infrastructure.
