The "high-pressure oxygen valve" developed by the "Langgao Valve" and an aerospace research base has successfully solved the problems of design, material selection, technology, machining, and quality control of the CL2500 pressure-grade oxygen valve. The valve has a two-way sealing function, through the 63.0MPa liquid strength and 35.5MPa high pressure gas sealing, sealing and other tests to achieve zero leakage, the test results are higher than the technical agreement requirements. The cleanliness of the valve after degreasing reaches ≤20mg/?
