As a pressure pipe component, valve controls the connection and cut-off of pipeline fluid. It is like a brake pad on an automobile. Once it is damaged, the consequences are unimaginable. Therefore, the performance and service life of the valve directly affect the normal operation of the pipeline system. Once the valve is damaged, the system must be shut down for maintenance. The loss is not comparable to the cost of several valves, so the quality and service life of the valve are particularly important.
The bellows stop valve is particularly outstanding in these two aspects. It has double seal to ensure zero leakage, and it meets the zero leakage standard of helium mass spectrometry detection, which is very safe and reliable. The number of cycles of bellows can reach more than 10000 cycles without damage, which is much longer than the service life of ordinary stop valve packing seal several times. In addition, the bellows valve can prevent the outside dust from entering the valve body and ensure the cleanliness of the medium. For example, under the working conditions of high-purity silica fume, pure oxygen, food and vacuum, the performance of bellows stop valve is very outstanding.
