1、Designation: F 993 86 (Reapproved 2006)An American National StandardStandard Specification forValve Locking Devices1This standard is issued under the fixed designation F 993; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification2covers the ap
3、plication, design, andmaterials for valve locking devices.1.2 Locking devices Types I and II described in thisspecification are designed to secure the valve in a fully openedor completely closed position.1.3 This specification does not apply to valves equippedwith locking devices from the valve manu
4、facturer, unless thisstandard is invoked in the procurement ordering data for thevalve or its locking device, or both.1.4 This specification is intended to supercede NASEAdrawing S4824-1385509. However, cancellation of that draw-ing and adoption of this specification can only be effected bythe navy.
