“ Reconditioning of Deteriorated Valves "


An efficient performance of a compressor completely depends upon a good condition of its valves.

Our well-equipped workshop and highly trained personnel carry out the overhauling procedures as follows:

  • Dismantle the deteriorated valves for visual inspection for any major damage, valve plate breakage, and excessive wear if any.
  • 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.
  • OPTIONAL: Coat valves with Xylan Coating to prevent clogging of parts and to enhance corrosion protection.
  • Pack and deliver the valves to customers, restoring its original designed performance characteristics.
