The original relief valves installed by the OEM are not required to be tagged and safety wired. Compressor relief valves that have been retested, or they are older than 3 years from the date of manufacture, shall have safety wires and tags installed)
-.032 inch minimum diameter for general purpose safety wiring
- Reflief vavle shall be safety wired in such a manner that an attempt to increase the set pressure will result in the tightening of the safety wire
- Wire installed with 5-8 twists per inch
- The termination of safety wire bent under and inward toward the relief valve
Metal tag attached to relief valve should indicate:
- Lift Pressure
- Test Date
