Related Model: Grove B7/B8 — Floating Ball Valve. Sizes 1/2"-8", Classes 150-1500. Application: Process isolation, chemical service.
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.
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.
Standard repair: 2-4 weeks — disassembly, inspection, machining, reassembly, testing
