How to judge the role of pneumatic butterfly valve brand?
1. It is strictly forbidden to install the pneumatic ball valve beyond the displacement limit. Valve pneumatic ball valve
2. The pipeline must have fixed support or fixed bracket, and the force of the fixed bracket must be greater than the axial force. During vertical installation and overhead installation, both ends of the product shall be installed with corresponding fixed support and stress support to prevent pulling off under pressure.
3. The installation bolts should be symmetrically and gradually pressurized and tightened to prevent local leakage.
4. Installation should be far away from heat sources, do not use media that do not meet the requirements of this product. 5. When installing the pneumatic ball valve, it is strictly forbidden to install it beyond the displacement limit.
6. The installation bolts should be symmetrical, and gradually pressurized and tightened to prevent local leakage.
For working pressure above 7.1.6mpa, elastic pressure pad shall be provided for the installation bolt to prevent the bolt from loosening during operation.
8. During vertical installation, both ends of joint pipe shall be supported by vertical force, and anti pulling device can be adopted to prevent pulling off under working pressure. 9. The installation position of pneumatic ball valve should be far away from heat source and ozone area. It is strictly forbidden to expose to strong radiation and use media that does not meet the requirements of this product. 10. It is strictly forbidden to cut the surface and sealing surface of pneumatic ball valve with sharp tools during transportation and loading.
