About ABS

The American Bureau of Shipping (ABS), is an impartial third-party certification service that provides third-party verification of a product's conformance to ABS rules and/or specified, acceptable national and international standards and/or specifications, and to verify the manufacture's use of appropriate, quality manufacturing systems.

There is a growing awareness of the importance of third-party certification, particularly in the oil and gas industry.  Prior to granting PDA certification on two models of the Guardian® reset relief valves, the ABS technical office reviewed the Guardian® product designs to validate compliance with industry codes and standards.  They also reviewed documented product performance tests and confirmed the integrity and functional performance of the Guardian® valves.  After a satisfactory technical evaluation, the ABS engineering department issued Marathon Valve a Product Design Assessment (PDA) on the 3" Guardian® CX 1,500 - 6,500 PSI reset relief valve and the 3" Guardian® RX 1,500 - 8,500 PSI reset relief valve.  ABS is the world's leading classification society providing services to the offshore industry, visit the official ABS website at www.eagle.org

As the OEM, Marathon Valve offers reset relief valves with the following certifications:

  • ABS Type Approval PDA certification
  • ABS / CDS certification
  • ABS surveyor witness testing (land and offshore drilling operations)

The 3" Guardian® CX 1,500 - 6,500 PSI reset relief valve and the 3" Guardian® RX 1,500 - 8,500 PSI reset relief valve has already been approved through the ABS Type Approval Program and carries the PDA certification.  Contact us for further information.
