Is it possible to reduce pressure and increase the actual flow rate? Or add a vent or return line to increase the flow rate through the check valve.
No, is it possible to change the type of check valve to improve the situation?
I think it would be better to use a check valve of one size smaller
It is still recommended to first analyze the reasons – whether it’s excessive resistance, a gas-liquid mixture, or some other factor. Once the root cause of the problem is identified, then measures can be taken.
If this issue has not occurred before, it indicates that the check valve is suitable for the pump’s outlet pressure. The current problem of insufficient outlet pressure is likely due to a fault with the pump itself or an increase in the viscosity of the material. Using a check valve of a smaller size might help, but this is not recommended; it is better to check the pump and the process materials instead
We have encountered similar situations as well. Perhaps you installed the level check valve vertically. Replacing the vertical safety valve might solve the problem
Try changing the one with buffering effect
