Wafer Style Axial Flow Check Valve Case Study
To understand the improved performance of an axial flow check valve in minimizing water hammer, you must consider the fundamental difference in the trim design. Just as ball valves, globe valves, gate valves, etc. have different flow characteristics, so do check valves.
We’ve put together a case study explaining how DFT wafer style axial flow check valves resolved an issue at a membrane plant in which the wastewater treatment facility was having problems with water hammering, resulting in the following:
- Check valve spring failure every 2-3 months
- Repair and replacement of check valve every 3-4 months
- Increased routine for tightening loosened flanging due to hydraulic shock in system
- Retuning of instrumentation due to hydraulic shock in system
- Loss of capacity due to increased maintenance routine
