Related Model: Velan Securaseal — Trunnion Ball Valve. Sizes 2"-36", Classes 150-2500. Application: Pipeline, fire-safe, double block & bleed.
Bonnet Bolt Relaxation: Bonnet bolts lose preload from thermal cycling, causing body-bonnet gasket leak. External leak visible at joint. More common in high-temperature service (>500°F).
Repair: Re-torque bonnet bolts to proper sequence. If gasket is damaged, replace spiral wound gasket. For chronic issues, upgrade to live-loaded bolting. Lead time: 1-3 days for re-torque, 1-2 weeks for gasket replacement.
Wedge Guided Wear: Guide rails on wedge gate wear from cycling, causing misalignment and difficulty operating. Wedge may cock and jam. Common in high-cycle applications after 8-10 years.
Repair: Re-machine guide rails and wedge guides. If wear exceeds 0.020", replace wedge assembly. Velan wedges are matched sets — both halves must be replaced together. Lead time: 3-5 weeks.
Emergency repair: 48-72 hours — expedited machining and assembly
