Related Model: Valbart Trunnion — Top Entry Ball Valve. Sizes 2"-42", Classes 150-2500. Application: LNG, cryogenic, pipeline.
Wedge/Disc Erosion: Gate or disc erodes from high-velocity steam or water. Wire-drawing creates channels that prevent tight shutoff. Extremely common in power plant extraction and drain valves after 5-10 years.
Repair: Weld overlay and re-machine seating surfaces. Stellite 6 hardfacing for steam service. If body erosion exceeds allowable wall thickness, valve must be replaced. Lead time: 3-6 weeks for weld repair.
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.
Cryogenic valve repair: 4-8 weeks — special materials, helium leak testing
