Third, if during the commissioning process, it is found that the pneumatic switch butterfly valve is slow in the initial position of opening the valve, and then it is fast. The main reason for this problem is that the valve is closed too tightly. Just reduce the cylinder stroke. It is easy to adjust the valve to open, and it can be closed without leakage. 　　　　

From the actual structure of the electric three-way ball valve, we can realize that this equipment can be divided into two structures of two seats and four seats, and each of the two structures is very good in terms of actual sealing. However, there are many types of actual channels, and both L-type and T-type models should be mastered more scientifically, so as to have a more comprehensive understanding of the basic mechanism of this product.
