One good reference on the behaviour of check valves is Fluid Transients in Pipelines by ARD Thorley published by D &L George. I think it may be out of print so you will have to scour the technical libraries.
www.valmatic.com has some technical papers on the subject.
The term "breaking pressure" is not one I have seen before. I have assumed it to mean the pressure at which the check valve will open. This data is normally provided by the manufacturer but if its an existing valve the above reference will assist.
If by "breaking pressure" you mean at what pressure will the body of the valve fail then the flange rating will be a good clue.
More information required.
