Secondly, if the product we buy is of high temperature style, its biggest advantage is its small size and reasonable design. It can withstand certain high temperature and is flexible when rotating. If you want to use this product, you will find that its service life will be very satisfactory and it can be used for a long time. It is similar to the plastic style electric butterfly valve in that maintenance is very simple and operation is not very troublesome. Analyzed from the internal structure, it adopts an eccentric structure. The biggest advantage of this structure is that it can reduce friction as much as possible when the seal ring of the product is working. In this way, the service life of the product is naturally extended.

After such a transformation, such problems never occurred again. In such a system, there are other factors that need to be taken into consideration, such as: materials cannot be directly rushed to the valve plate of the valve when they are put into the trolley from above (this impact force will also make the valve cannot be closed tightly), and the static pressure of materials must not exceed the design bearing pressure of the pneumatic butterfly valve, etc. The difference between a control valve and an ordinary manual valve is that you cannot treat it as an isolated element, but must consider it as a part of the entire automatic control system. Many problems in the use of control valves are not the problem of model selection and configuration, but because the user's lack of understanding of the control valve causes the control valve to fail to debug and cooperate well with the control system. As long as we recognize the key point of the problem, correctly select the valve, and properly debug the control valve in the system commissioning stage, we can greatly reduce the failure rate and make the automatic control system operate stably for a long time. We have discussed a lot about the use of pneumatic butterfly valves in gas and liquid media. Because pneumatic butterfly valves are not used for solid materials (such as dust and stone powder), there are still many aspects worth discussing in the selection and use of pneumatic butterfly valves.
