7.5 performance requirements
7.5.1 Set pressure
Adjust the valve set pressure to the nameplate, within tolerances listed
below.
7.5.1.1 ASME BPVC Section- I Applications:
set pressure, psig [barg]
Tolerance
≤ 70 [4.83]
± 2 psig [0.14 barg]
> 70 [4.83] and ≤ 300 [20.68]
± 3% of set pressure
> 300 [20.68] and ≤ 1000 [68.95]
± 10 psig [0.69 barg]
> 1000 [68.95]
± 1% of set pressure
7.5.1.2 ASME BPVC Section- VIII Applications:
set pressure, psig [barg]
Tolerance
≤ 70 [4.83]
± 2 psig [0.14 barg]
> 70 [4.83]
± 3% of set pressure
7.5.2 Blowdown
set pressure, psig [barg]
Maximum blowdown
< 67 [4.62]
4 psig [0.28 barg]
≥ 67 [4.62] and < 250 [17.24]
94% of the actual set pressure
≥ 250 [17.24] and < 375 [25.85]
15 psig [1.03 barg]
≥ 375 [25.85]
96% of the actual set pressure
7.5.3 Minimum required lift

Min. lift (inches)
note:
For ASME BPVC Section I applications, minimum blowdown for all
safety or safety relief valves shall be 2 psig [0.14 barg] or 2% of the set
pressure, whichever is greater.
