What if my valve is damaged or non-functional?
We still buy it. Non-functional valves have value for parts, refurbishment, or material recovery. A 20" WCB Carbon Steel valve body alone has significant scrap metal value.
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 Cracking (Thermal Fatigue): Valve body develops cracks from repeated thermal cycling (startup/shutdown). Most common in main steam gate valves and feedwater check valves. Can lead to catastrophic failure if undetected.
Repair: NDE inspection (UT, MT, PT) to map crack extent. Weld repair if cracks are shallow and in non-critical areas. Body replacement if cracks penetrate >50% wall thickness. Lead time: 4-12 weeks depending on severity.
Cryogenic valve repair: 4-8 weeks — special materials, helium leak testing
