Lifting Device as required by the ASME
ASME Section VIII: UG136(3)
Each pressure relief valve on air, water at the valve inlet that
exceeds 140°F (60°C), excluding over-pressure or relief
events, or steam service shall have a substantial lifting device
which when activated will release the seating force on the disk
when the pressure relief valve is subjected to a pressure of at
least 75% of the set pressure of the valve.
The lift lever may be omitted providing:
1. The user has a documented procedure
and an associated implementation program for the periodic removal
of the relief valve for inspection, testing, and repair.
2. The user specifies that no test lever be supplied.
3. The user shall obtain permission to omit the lifting lever
(device) from the authority having jurisdiction over the
installation of pressure vessel.
These rules apply to valves installed in ASME Section VIII applications.
All valves used in ASME Section I (Boiler) applications require lifting levers except for those valves used in organic fluid vaporizer service.
