API RP 6DR (R2020)

This recommended practice provides guidelines for the repair and remanufacture of steel ball, check, gate, and plug valves normally used in pipeline applications, as defined by API 6D.

This recommended practice covers repair or remanufacturing of end user’s (owner’s) valves for continued service in the owner’s production applications. It does not cover repair or remanufacture of used or surplus valves intended for resale.

Repaired or remanufactured valves may not meet API 6D and/or the OEM original product definition (OPD) for new valves.

The owner is responsible for the correct application of valves repaired or remanufactured per this document.

Field repair is outside the scope of this document.
