Check valves prevent reverse flow without any external actuation, which makes them simple to buy and easy to specify wrongly. The failure people meet in service is slam: when a pump trips, a slow-closing disc lets flow reverse before it seats and shuts against a returning column, producing a pressure surge that damages pipework. Swing, dual plate, axial nozzle and lift designs close at different speeds, so the pump and the line behaviour matter as much as size and class.
The more of this you send, the closer the first quotation lands.
