Related Model: Grove B7/B8 — Floating Ball Valve. Sizes 1/2"-8", Classes 150-1500. Application: Process isolation, chemical service.
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.
Body/Bonnet Gasket Leak: Spiral wound gasket between body and bonnet develops leak due to bolt relaxation from thermal cycling. External leak visible at body-bonnet joint.
Repair: Replace spiral wound gasket (typically 316SS/graphite). Re-torque body bolts to proper sequence and values. Lead time: 3-5 days.
Complete overhaul: 4-8 weeks — full teardown, all internals replaced, hydro tested
