Low-temperature ball valve

Low-temperature valves include low-temperature ball valves, low-temperature gate valves, low-temperature stop valves, low-temperature safety valves, low-temperature check valves, low-temperature butterfly valves, low-temperature needle valves, low-temperature throttle valves, low-temperature pressure reducing valves, etc. They are mainly used in ethylene, liquefied natural gas facilities, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low-temperature storage tanks and tankers, pressure adsorption oxygen generation, etc. The output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc. are not only flammable and explosive, but also will vaporize when heated, and their volume expands hundreds of times.

The material of liquefied natural gas valves is very important. If the material is not qualified, it will cause leakage of the shell and sealing surface or internal leakage; the comprehensive mechanical performance, strength and stiffness of the components cannot meet the usage requirements and may even break. This leads to leakage of the liquefied natural gas medium and causes an explosion. Therefore, in the process of developing, designing and researching liquefied natural gas valves, the material is the most crucial issue.

After many years of manufacturing, we have accumulated rich experience. From design, process to manufacturing, it has become increasingly mature, and a series of low-temperature valve products have been developed.

Low-temperature valves include low-temperature ball valves, low-temperature gate valves, low-temperature stop valves, low-temperature safety valves, low-temperature check valves, low-temperature butterfly valves, low-temperature needle valves, low-temperature throttling valves, low-temperature pressure reducing valves, etc. They are mainly used in ethylene, liquefied natural gas facilities, natural gas LPG LNG storage tanks, receiving bases and satellite stations, air separation equipment, petrochemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide low-temperature storage tanks and tankers,变压吸附 oxygen generation equipment， etc. The output liquid low-temperature media such as ethylene， liquid oxygen， liquid hydrogen， liquefied natural gas， and liquefied petroleum products are not only flammable and explosive， but also will vaporize when heated， and during vaporization， the volume expands hundreds of times.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition
