Low Temperature Ball Valve

7 products found

A low temperature ball valve (cryogenic ball valve) is a highly engineered quarter-turn rotary valve designed to provide bubble-tight isolation for sub-zero liquefied gases down to -196°C without seal binding or structural failure. To protect critical mechanical components, the valve is manufactured with an extended "long-neck" bonnet that moves the stem packing and automated actuator safely away from the freezing process media, maintaining a pocket of vaporized gas that prevents the seals from freezing and leaking. Available in floating or trunnion-mounted (fixed) configurations, the valve utilizes precision-ground spherical balls rotating against high-purity polymer seats like PTFE or PCTFE, incorporating an automatic internal cavity pressure relief hole to prevent explosive overpressure caused by liquid expansion when trapped media warms up. Cryogenic plant operators and gas infrastructure procurement managers can ensure safe low-temperature fluid containment and prevent stem-freeze leaks by importing certified low temperature ball valves directly from leading manufacturers in China via our advanced B2B commercial platform.
