Expert Repair & Failure Analysis

Related Model: Velan Dual Plate — Wafer Check Valve. Sizes 2"-48", Classes 150-2500. Application: Low pressure drop, non-slam.

What Usually Goes Wrong

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.

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.

Repair Lead Time

Standard overhaul: 3-5 weeks — full inspection, machining, hydro test
