Dear All,

I have put a concentric suction & delivery valve for my 50HP reciprocating compressor. I have found a significant dip in my FAD. I suspect the leakage of concentric valve as one of the reason since it was failing in the pressure test in which the specification is designed by other concentric valve supplier.

I want to know "Is there any standard testing methods are availble for concentric valves?" or Supplier to supplier, the testing method will vary?

What will be optimum method to check the leakage of concentric valves?

Thanks & regards,

GVe
