Check Valve Slam: Swing or tilting disc check valve slams closed causing water hammer. Damages disc, hinge pin, and downstream piping. Caused by rapid flow reversal (pump trip).
Repair: Replace disc and hinge pin. Install dashpot or spring-assisted closure. For severe cases, replace with non-slam check valve (DFT or Flowserve dual-plate). Lead time: 2-6 weeks.
Backseat Leak: Backseat fails to seal when valve is fully open, allowing packing to be pressurized. Prevents online packing replacement. Common in older Edward gate valves.
Repair: Re-machine backseat in-situ or remove valve for shop repair. Backseat lapping requires specialized tooling. Lead time: 2-4 weeks.
Weld overlay repair: 4-8 weeks — preheat, weld, PWHT, machining, NDE
