• Punch mark valves individually with Job number and serial number.
• De-grease all components that will be re-used for the reconditioned valves
• Sandblast all components with glass-bead media to obtain a clean and rust free surface finish.
• Check for non-visual cracks in the seats, guards and plates by observation under ultraviolet light.
• Seats, guards and Centre bolts will be replaced if found cracked, damaged or beyond repair
• Prepare inspection report and quotation.
• Machining, grinding and/or lapping the valve seat to obtain its original tolerance and flatness.
• Flatness check of the valve seat by observation under Optical Flat Monochromatic light.
• Assemble the valve with new sealing and spring elements as per OEM Drawing and parts list.
• Pneumatic Pressure Test each valve under simulated operating conditions to check for leakage if any, spring load and valve lift.
