2) Valve Details

Crogenic Forged Floating Ball Valve 304 Body PN16 DN25 1. Reduced bore design

Cryogenic ball valves are built to help transport and store cryogenic gasses safely and efficiently. Reduced bore open according to API 6D standard.


Crogenic Forged Floating Ball Valve 304 Body PN16 DN25 2. Bolted bonnet connection

ZJCLV ball valve adopts the standard bolts and nuts. It could extend the valve longer service life.


Crogenic Forged Floating Ball Valve 304 Body PN16 DN25 3. Ectended stem structure

Crogenic ball valve stem is designed to be extension stem structure that is easy to keep cold according to different operating temperature requirements, so as to ensure that the temperature at the bottom of packing is kept above 0°C to prevent the temperature being too high.


Crogenic Forged Floating Ball Valve 304 Body PN16 DN25 4. Excellent PCTFE seat seal

Sealing is reliable and smooth flow channel so that the floating ball valve can keep in good condition when working for a long time.


3) Usage

Cryogenic ball valve is mainly used in ethylene, liquefied natural gas and other chemical plants, the output of liquid low temperature medium such as ethyfene, liquid oxygen, liquid hydrogen and so on. This kind of medium is not only inflammable and explosive, but also to gasity when heating up. gasification expands the body hundreds of times. And these medium permeable force is strong, easy leak, process makes more dificult.
