Description / Abstract:

This specification2 covers the application, design, and materials for valve locking devices.

Locking devices Types I and II described in this specification are designed to secure the valve in a fully opened or completely closed position.

This specification does not apply to valves equipped with locking devices from the valve manufacturer, unless this standard is invoked in the procurement ordering data for the valve or its locking device, or both.

This specification is intended to supersede NASEA drawing S4824-1385509. However, cancellation of that drawing and adoption of this specification can only be effected by the navy.
