How to judge the principle and advantages of pneumatic ball valve, what are the brands?

1. When installing the pneumatic ball valve, it is not allowed to weld the temporary support on the wave node. When hoisting, the sling should not be tied to the wave joint.
2. When installing copper pneumatic ball valve, its straight pipe length shall not be less than 100 mm
3. The pipe fixed support installed on the supports and hangers is set to ensure the reasonable distribution of the thermal expansion of the pipeline between pneumatic ball valves. When the temperature change causes the expansion or contraction of the pipeline, the fixed support can prevent the pipeline from displacement at this point. The fixed bracket matching with the compensation device should be fixed before pre stretching (compression) to make the pneumatic ball valve compensation device play its due role. Only one fixed support can be installed on the straight pipe with displacement without compensation device, otherwise the displacement will be hindered.
