Related Model: Edward Univalve — Forged Steel Gate Valve. Sizes 1/2"-2", Classes 800-4500. Application: High pressure instrument isolation.
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.
Body replacement: 8-16 weeks — casting procurement, machining, assembly
