Description / Abstract:

This specification establishes design validation requirements for API 6A surface safety/underwater safety valves (SSV/USV) and associated valve bore sealing mechanism(s) for Class II and Class III. These classes are intended for use if substances such as sand can be expected to cause an SSV/USV valve failure. Class III adds requirements for the validation of the valve bonnet assembly inclusive of stem seals and may be selected by the user/purchaser. Validation to Class III also validates the same SSV/USV for Class II.

NOTE Previous editions of this document included reference to and requirements for verification to PR1, standard service (Class I).
