API Spec 6AV1

Click here to purchase
There are three service classes – Class I, Class II, and Class III – for API 6A surface safety valve (SSV), underwater safety valve (USV), or boarding shutdown valve (BSDV). This standard establishes sandy service design validation for valves to meet Class II and Class III.

Class II is intended to validate the valve bore sealing mechanism if substances such as sand can be expected to cause safety or shutdown valve failure.

Class III adds additional requirements and validation of the bonnet assembly inclusive of stem seals and may be selected by the user/purchaser. Validation to Class III also validates the same SSV/USV/BSDV for Class II in accordance with scaling limitations specified in the document.

The validation requirements in this standard are not represented as duplicating actual well conditions. For actuated valves, validation of the actuator is outside the scope of this standard.
