We are one of the
leading valve brand
in cryogenic valve series

A plug valve is a rotary valve with a closing member or plunger. During operation, a 90-degree rotation connects or separates the passageway on the plug with the passageway on the valve body, achieving opening or closing. The plug can be cylindrical or conical. The passageway in the former is generally rectangular, while the passageway in the latter is trapezoidal. It features a simple structure, rapid opening and closing, and low fluid resistance, making it ideal for shutting off and connecting media, diverting flow, and sometimes also used for throttling.

Cryogenic valves are industrial valves specifically designed for media temperatures ranging from 40°C to 196°C or even lower. They are suitable for ultra-cold fluid systems such as liquid oxygen, liquid nitrogen, liquefied natural gas, and ethylene. They utilize cryogenic materials and specialized structural designs to ensure reliable sealing and stable operation in extremely low-temperature conditions. Common types include cryogenic ball valves, gate valves, globe valves, and butterfly valves, and are widely used in aerospace, nuclear industry, petrochemical industry, and natural gas industries.

Cryogenic valves are specialized valves designed for use in media temperatures below 40°C. They are widely used in cryogenic applications such as liquefied natural gas (LNG), liquid nitrogen, and liquid oxygen. Cryogenic valves require extremely high sealing, thermal insulation, and operational reliability, making them key equipment in cryogenic storage and transportation systems in industries such as energy, chemical, and air separation.
