Generally, the operator is not familiar with the control system and manual operation system of the pneumatic butterfly valve, so the pneumatic butterfly valve will be damaged due to improper operation during the operation. Therefore, the operators who operate the pneumatic butterfly valve and other related valves need professional personnel for training, In order to prevent improper operation during the whole construction process, which may damage the product equipment, cause material omission or material damage, and finally bring some property losses to the enterprise and the country.

How to determine the length of pneumatic butterfly valve?
The length is very important. We often do not do this work well when we confirm the length of the pneumatic butterfly valve, so that the pneumatic butterfly valve in working condition often has problems of one kind or another due to the improper length. For example, if the pneumatic butterfly valve used in the pipeline system is too long, it will produce greater fluid resistance, etc. Therefore, it is very important to confirm the length of the pneumatic butterfly valve. Next, we will introduce the methods for determining the length of pneumatic butterfly valves in several different application places.
1. The length of gooseneck used as compensator depends on the size of drift diameter. In the pipeline system, if the compensation amount of one compensator is not enough, two or three compensators can be used. If it is restricted by the space location conditions, it is impossible to install a large number of compensators, and the compound structure can be selected.
2. The length of the pump inlet and pump outlet receiving for vibration and noise elimination depends on the size of its diameter, that is, if the diameter is less than or equal to 100mm, L is the length of the flexible section of the compensator or pneumatic butterfly valve; Is the diameter of compensator or pneumatic butterfly valve.
3. Angular displacement, the length depends on the size of its practical bending radius and displacement angle. The length of the pneumatic butterfly valve with horizontal displacement depends on its practical bending radius and horizontal displacement. The tangent section refers to the intermediate transition section of two pipes with the same radius and in different directions when the pneumatic butterfly valve moves laterally.
