SS304 DN25 Cryogenic Emergency Gas Line Shut Off Valve for LNG LN2 LAr


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.



Cryogenic valve standards and product structure:


1. Design: API6D, JB / T7749


2. Routine inspection and test of valve: According to API598 standard.


3. Valve low temperature inspection and test: According to JB / T7749.


4. Drive mode: manual, bevel gear drive and electric drive.


5. Valve seat form: The valve seat adopts welding structure, and the sealing surface is welded with cobalt-based hard alloy to ensure the sealing performance of the valve.


6. The damper adopts an elastic structure, and a pressure relief hole is designed at the inlet end.


7. One-way sealed valve body is marked with flow direction mark.


8. Low temperature ball valve, gate valve, globe valve and butterfly valve adopt long neck structure to protect packing.


9. Ultra-low temperature ball valve standard: JB / T8861-2004.
