Compressor Valves Rider Rings

To meet the varied sealing and piston support requirements of Reciprocating Compressors, CVE Manufactures a wide variety of Piston and Rider Rings up to 42" diameter. These rings are offered in a broad range of materials to suit the specific requirements.

CAST IRON : We manufacture piston rings from graded cast iron which provide good sealing over a wide temperature range in applications where adequate lubrication can be provided. All of our cast iron rings are heat tensioned.

BRONZE : Our Bronze Piston Rings offer great wear resistance and are preferred for high temperature and pressures where lubrication may be marginal. The most commonly used Bronze Grade is 80:10:10 (CU-SN-PB) Chilled Casting. Various other grades are also available for different service conditions.

CARBON FILLED TEFLON : Piston rings manufactured from Carbon filled Teflon offers good compressive and shear strength, hardness and wear resistance. They are particularly effective in non-lubricated services and have got excellent corrosion resistance.
