Mainly applied in LNG storage and transportation, liquefied gas industry, petrochemical plant, air separation unit and cold‑medium pipeline system. Used for cut‑off and isolation control of liquefied natural gas, liquid nitrogen, liquid oxygen and other ultra‑low temperature media.
Cryogenic Stainless Steel Ball Valve realizes opening and closing by 90‑degree rotation of ball core. The extended bonnet structure reduces the influence of low temperature on packing and upper components, ensures reliable sealing under cryogenic environment. When ball through‑hole aligns with pipeline channel, medium flows through; rotate 90 degrees to block passage and complete medium shut‑off.
