  • Product Profile

    Low temperature ball valve is mainly suitable for ethylene, liquefied natural gas and other chemical devices, the output of liquid low temperature medium such as ethylene, liquid oxygen, liquid hydrogen, etc. This kind of medium is not only flammable and explosive, but also when heating up to gasification, gasification to make the machine expansion hundreds of times. And these media penetration force is strong, easy to leak, processing and manufacturing is more difficult.
