Bellows valve in the use of a lot of fault, when there is a corresponding fault when we have the corresponding solution, here we will look at the bellows Valve Common Fault Solution. Although the bellows stop valve can achieve a hard seal to achieve the principle of no leakage, but once the bellows break, the valve is basically useless, there is also a little backup packing on the outside, simply can not withstand, so when we use, must be careful, do not quickly switch this valve, once the bellows damaged, there will be uncontrollable consequences! Bellows valve as long as anti-rotation reliable, bellows interface design reasonable, reliable weld, the general bellows will not break. Now the main imitation ARI is made in some places not in place and caused. We have made no less than 40,000 valves, and there has not been any leakage at the bellows. It is possible that some bellows stop valves are not of good quality. One is on the auxiliary line of the regulating valve, and there is a problem that can not be controlled, it's unresectable. Very passive! The above is about the common failure of the bellows cut-off valve method, I hope to help you.
