Reconditioning of Spare Parts

Reconditioning of the compressor is essential for keeping the valves in good condition and to enhance the performance of the compressors. If the compressors are not kept under maintenance on a regular basis, it not only leads to deterioration of the valves but also raises the operating costs. Compared to entirely replacing the valves, a far better solution is to recondition them. One of ORIENTAL’s initiatives is to recondition expensive valves which form the arteries of a compressor during hours of predicament.

  • De-greasing, washing with environment friendly solvent & blasting
  • Inspection and Clearance
  • Reconditioning (including machining / lapping) while keeping design dimensions intact
  • Replacing with new internals
  • Assembly and air leak testing
  • Packaging and labeling


The initiation of the reconditioning process begins with an elaborate and intricate procedure of inspection and clearance. The valves which are subjected to refurbishing are sent to Oriental workshops to be dismantled, and cleaned for inspection. Major parts like seats and guards are thoroughly inspected for any kind of fault or erosion. Any valves suspected of even minor flaws are exposed to magnetic particle testing, which is used to reveal hairline cracks.


It is prerogative of oriental to take utmost care of the valves for the benefit of the compressors as well as the client. At Oriental, the valve seats and guards are first subjected to short peening in order to cleanse the parts of foreign sediments and deposition. Then, the parts are re-machined (following its original design norms) such that its initial tolerance and capacity is maintained. All valve seat-sealing faces are lapped to ensure flatness and precision.

To ensure precision of the flatness and the perfection of the finished result, all the valve seat sealing faces are lapped as per the standards.

  • Old components can be separated. If the customer demands, the scrapped components can be returned.


Replacement for internal components includes valve plates, valve springs, lift washers as well as discharge valve studs


All the components are screened through the process of leak testing. Compressed air is passed through the valves and the valves are given the green signal only if the leaks are within permissible limit. The leak test can be performed in the presence of a representative of the client company if prior arrangements are made.


The reconditioned valves are provided with coats of chemicals, which help prevent the formation of rust and the effects of corrosion. Packing and labeling of each part is meticulous to protect goods during transit and storage.

Benefits to our clients:

  • The customer can achieve savings up to 60% in several cases.
  • Minimum assurance and satisfaction guarantee for 6 months (or 2500 working hours) for any reconditioned valves purchased from Oriental. Assurance and satisfaction guarantee for a much longer period under normal circumstances.
  • Users informed of any other abnormalities that surface during the inspection process./li>
