Maintenance of Ball Valve packing
The packing is directly related to whether the Ball Valve leaks when it is switched. If the packing fails and causes leakage, the Ball Valve will also fail, especially the Ball Valve of the urea pipeline, because its temperature is relatively high, the corrosion is relatively serious, and the packing is easy to age. Strengthening maintenance can extend the life of the packing.
Precautions for selecting and replacing Throttle Valve
