Can the DN300 pneumatic diaphragm regulating valve be reversely purged when drying the pipeline?
Thread Content
I encountered a problem during drying of the project. When writing the drying plan, I wanted to use dry air to purge the end of the natural gas station in reverse direction. Can the DN300 pneumatic membrane regulating valve be purged in reverse direction when drying the pipeline? Will it be damaged? What is the flow rate of dry air?

The third floor is right. You can turn off the shut-off valves at both ends of the regulating valve and take a bypass. Or simply remove the regulating valve and add a short pipe to the pipeline to facilitate purging. It is absolutely not allowed to use a regulating valve to purge the pipeline, let alone a flow rate of 30M/S. Otherwise, the regulating valve will be blown out, or the sealing surface of the regulating valve will be scratched by dirt. In that case, the consequences will be serious. Remember, remember, remember!
No instruments can participate in pipe purging. We are in the wrong place on the second floor. We should go to the advertising area. What do you think, administrator?
