Issues with selecting a breakdown-proof (overvoltage protection) drain?
Thread Content
Dear all, I have a question regarding the selection of a backflow prevention (overpressure protection) drain valve: The normal operating pressure in the pipeline is 10 KPa, but due to fluctuations in process conditions, instantaneous peak pressures can reach 200 KPa, which causes the current drain valves to fail from time to time. What water seal height should be chosen for such a drain valve, and what value is appropriate for the high-pressure protection setting? Also, I would like to know how effective the drain pumps with overpressure protection that everyone is using are; please let me know which company’s products they are. Thank you!
Looking forward to the answers from relevant experts. Thank you!
