Precautions for installation of pneumatic ball valve

1. Before installation, check the pneumatic ball valve, check the specifications and models, and identify whether there is any damage, especially for the pneumatic components. Check whether it is skewed, damaged or deformed, because the goods will inevitably fall or be squeezed by other goods during transportation.
2. Then remove the debris in the valve. Under normal circumstances, the pneumatic ball valve is covered with a dust bag, but when the pneumatic ball valve is packaged, there will inevitably be some shock-absorbing fillers such as cardboard and foam in the wooden box. High requirements like pneumatic vacuum ball valve will definitely affect its normal operation.
3. When lifting the pneumatic ball valve, the rope should not be tied to the handwheel or valve stem, so as not to damage these parts, but should be tied to the flange.
4. For the pipeline connected to the pneumatic ball valve, it must be cleaned. Be sure to clean up. Be sure to clean up. In many cases, the installation and construction site will ignore this link, please keep it in mind.
5. Compressed air can be used to blow away iron oxide chips, mud sand, welding slag and other sundries. These debris not only easily scratch the sealing surface of the pneumatic ball valve, but also large particles of debris (such as welding slag) can also block the small pneumatic ball valve and make it invalid. When installing a pneumatic threaded ball valve, the sealing packing (line hemp plus aluminum oil or PTFE raw material tape or sealant, etc.) should be wrapped on the pipe thread, and should not get into the pneumatic ball valve to avoid accumulation in the valve. Affect the media flow.
6. When installing the pneumatic flange ball valve, pay attention to tighten the bolts symmetrically and evenly. The flange of the pneumatic ball valve must be parallel to the flange of the pipe, and the clearance is reasonable, so as to avoid excessive pressure and even cracking of the pneumatic ball valve. Special attention should be paid to pneumatic ball valves of brittle materials and low-strength plastics.
7. Some pneumatic ball valves must also have external protection, which is heat preservation and cold preservation. In the insulation layer, sometimes a hot steam pipeline is added. What kind of pneumatic ball valve should be kept warm or cold depends on the production requirements.
8. Some pneumatic ball valves are installed in the open air, and are greatly affected by wind, sun, and temperature difference between day and night, especially for the service life of some pneumatic components with relatively high precision. It is recommended to add a protective cover device.
