2) Valve Details

Crogenic Floating Ball Valve 316L Body PN40 DN40 1. Full bore design

2 Piece type;

Full-bore design provides big flow control;

Cryogenic ball valves are built to help transport and store cryogenic gasses safely and efficiently.


Crogenic Floating Ball Valve 316L Body PN40 DN40 2. Bolted bonnet connection

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


Crogenic Floating Ball Valve 316L Body PN40 DN40 3. Extended 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.

The yoke design is convenient for assembling worm gear, pneumatic, electric,  hydraulic and pneumatic & hydraulic actuators.


2) 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.
