Related Model: Grove B7/B8 — Floating Ball Valve. Sizes 1/2"-8", Classes 150-1500. Application: Process isolation, chemical service.
Gate/Ball Stuck: Gate or ball becomes stuck due to scale buildup, corrosion, or debris between seat and gate. Valve won't open or close fully. Common in valves left in one position for extended periods.
Repair: Inject penetrating lubricant through grease fitting. If stuck, may require partial disassembly. For Pow-R-Seal valves, the expanding mechanism may need rebuilding. Lead time: 1-2 weeks.
Seat Damage/Scoring: Metal seats develop scoring from pipeline debris (sand, scale, weld slag). Causes through-leakage that worsens over time. Most common in Pow-R-Seal valves after 5-7 years of service.
Repair: Seat lapping or replacement. Remove gate, lap seat faces to 2-3 helium light bands flatness. If scoring exceeds 0.010", seats must be replaced. Lead time: 2-3 weeks for seat machining.
Complete overhaul: 4-8 weeks — full teardown, all internals replaced, hydro tested
