Lanzhou High Valve Successfully Developed Large Diameter Hyperbaric Oxygen Valve

Lanzhou High-Pressure Valve Co., Ltd. and an aerospace research base have worked together for more than three months to overcome many world-class technical problems in the “high-pressure oxygen valve” and successfully developed the CL2500 large-diameter electric nickel alloy “high-pressure oxygen valve”. . On December 4th, the first batch of “very high pressure oxygen valves” passed inspection and acceptance by the use unit and were shipped and shipped in a box, which will be installed on China’s national defense engineering construction projects.
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/?
