Common failures & inspection points

Unauthorized modifications or welded attachments to valve cap

Visual inspection for welded nuts, brackets, or tools attached to valve cap; Verify no third-party modifications have been made to facilitate servicing

Corrosion, pitting, cracks, or visible surface damage on valve body

Visual inspection of body condition for corrosion, external damage, leaks; Check for discoloration or deformation indicating stress or age degradation

Seal integrity and weeping/leaking from bonnet flange or seams

Inspect seal condition for wear, cracking, deterioration; Check bonnet flange and valve body seams for minor seepage indicating seal degradation; Verify seals are properly seated and aligned

Manual lift lever malfunction or failure to operate properly

Perform manual lift test to verify lever operates freely and valve responds to manual pressure activation; Check for stiffness, resistance, or complete non-response

Set pressure or vacuum drift due to corrosion or internal component degradation

Conduct pressure test rig testing to verify set pressure/vacuum settings match documentation; Use Fort Vale Pressure/Vacuum Test Rig for calibration verification (6-monthly basis recommended)
