The flapper type check valve can be used as a back up flapper valve on an Edson Diaphragm Pump or the Edson Vacuum System transfer tanks. It can also be used to insure no back flow on a pump out hydrant. Made of marine grade bronze with 1.5" FNPT (Female National Pipe Threads) on each end, it is very durable for those demanding conditions.
