Why High Neck Valve Caps Are Not an Option, but a Necessity in Cryogenic Applications

Valve /

Cryogenic valves are widely used in industries dealing with extremely low-temperature media such as liquid oxygen, liquefied natural gas (LNG), and others. These media are not only highly flammable and explosive, but they also vaporize rapidly upon warming, causing a volume expansion of several hundred times, which creates significant safety risks. So, why are high
