Organization: API
Publication Date: 1 July 2018
Status: active
Page Count: 32
scope:

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.

Validation of the actuator is outside the scope of this standard.

NOTE This standard does not contain the validation requirements for Class I safety valves.
