Application Scope Of Cryogenic Solenoid Valves

Cryogenic solenoid valves are mainly used in cryogenic working conditions with a temperature of -196℃. As common pipeline switching components in automatic control systems, they are widely applied in pipeline devices of industrial sectors such as refrigeration equipment, food machinery, air separation equipment, petrochemicals, metallurgy, exhaust gas separation equipment, ethylene plants, liquefied natural gas (LNG) plants, cryogenic storage tanks and tank trucks, pressure swing adsorption oxygen generation equipment, liquid nitrogen storage equipment, and cryogenic test devices. They realize the automatic control of various media such as gases, liquids, and oils in the system, achieving energy saving and process control automation.

Performance Features Of Cryogenic Solenoid Valves

Suitable for both liquid and gaseous media, expanding the application range of the valve.

Adopts imported original sealing materials, with a service life ten times that of similar products.

Processed by high-precision CNC machine tools, ensuring the accuracy and flexibility of the solenoid valve.

Equipped with a special plastic-sealed coil, improving the valve’s reliability and providing waterproof and moisture-proof performance.

Horizontal design with the coil installed upward; fast response speed.

The valve body is manufactured using a hot forging process, featuring an aesthetic and compact appearance.
