【Product Introduction】

The Cryogenic Ball valve suitable for medium temperature of - 40 ℃ ~ - 196 ℃。This ball valve adopts strict manufacturing process and special equipment to carry out strict quality control on the processing of parts. After special low-temperature treatment, the rough machined parts are placed in the cooling medium for several hours (2-6 hours) to release the stress, ensure the low-temperature performance of the material, and ensure the finishing size, so as to prevent the leakage caused by the deformation caused by the temperature change when the valve is in low-temperature condition.

Cryogenic Treatment Way

The cryogenic treatment of cryogenic ball valves shall be applied to the main components of any cryogenic valves at -101 ° C and below, or as required by the technical agreement.And improve the reliability of the valve under low temperature conditions;

1、Before the roughing is completed, "cryogenic treatment" is carried out in a low temperature liquid nitrogen tank that is 100% immersed in -196 °C. 

2、Immerse the parts in a liquid nitrogen tank for adequate cooling. 

3、When the part temperature reaches -196 ° C, keep the temperature for 1-2 hours (or according to the requirements of the corresponding technical agreement), then remove the box and naturally heat to room temperature.

4、The purpose of "cryogenic treatment" is to eliminate the martensite transformation of the Cryogenic Ball Valve material and the sufficient shrinkage deformation of the material at ultra-low temperatures.

5、Thereby eliminating the potential hazards affecting the dimensional accuracy of the cryogenic valve seal.
