The purpose of this specification is to establish requirements to:
-verify the basic performance requirements (PR1) standard service surface safety valves (SSV) and underwater safety valves (USV) valve design;
-verify the basic SSVAJSV actuator design;
-verify the basic PR2 sandy service SSVNSV valve design; and,
-to demonstrate the verification testing covered by this specification that is required to qualify specific valve bore sealing mechanism manufactured under API Spec 6A for PR2 sandy service safety valves.
Included are minimum acceptable standards for verification testing of SSVs AJSVs for two performance requirement levels. To qualify, a SSVNSV valve must pass the verification test specified in Section 4. The two performance requirement leves are as follows.
-PRI Standard Service-This performance requirement level of SSV/USV is intended for use on oil or gas wells that do not exhibit the detrimental effects of sand erosion or fouling; and
-PR2 Sandy Service-This performance level of SSVNSV is intended for use on oil or gas wells where a substance such as sand coud be expected to cause a SSVAJSV valve failure.
This valve must also meet the requirements of performance level PRI Standard Service.
