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