Flange Type Emergency Cryogenic Shut Off Valve Ss304 Ss316 Dn10 - Dn100mm

Manufacturing and testing of cryogenic valves:

Liang Chuan Company strict manufacturing process and special equipment are adopted for the produced low-temperature valves, and the quality of parts is strictly controlled. After special low temperature treatment, the rough 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 finished size to prevent the valve from working in low temperature conditions. Leakage due to deformation due to temperature changes. The valve assembly is also different from ordinary valves. Parts need to be strictly cleaned to remove any oil stains to ensure performance.

Notes When Use

1 . It should ensure that the pipe is blown clean before installation.

2 . When installing, make sure that the flow direction indicated by the arrow on the valve body should be consistent with the flow direction of the fluid.

3 . This valve has been degreased. Store and keep clean when installing.

4 . After the pipeline construction is completed, all the valves on the pipeline should be opened, and the residue in the pipeline should be thoroughly and thoroughly kept to ensure that the pipeline system is clean and free of debris.

5 . The installation system diagram with the oil-free requirements should be degreased.

6 . Slowly open and close during use.

7 . If the precision parts such as the valve disc, valve seat and valve stem are worn or damaged, it must be repaired and replaced in time.

8 . For parts such as gaskets and sealing materials, replace them with new ones each time.
