Examples
Pneumatic: Hydraulic:
Establish cracking pressure setting of 1/2" valve for Find amount of pressure increase above 24.8 Bar
flow of 70 SCFM at 27.6 Bar (400 PSI) pressure: (360 PSI) cracking pressure when flow through
1. Project 70 SCFM on vertical scale. 3/4" valve is increased to 54 LPM (14 GPM):
2. Project 27.6 Bar (400 PSI) scale horizontally inter- 1. From 360 on vertical pressure scale, follow
sectiong 1. 3/4" curve until it intersects with the vertical line
3. Project line parallel to curves back to vertical line 1. representing 54 LPM (14 GPM).
4. Read cracking pressure setting: 24.8 Bar (360 PSI). 2. Project intersecting point horizontally and read
pressure, i.e., 29 Bar (420 PSI).
3. Accumulated Pressure:
420 minus 360 = 4.1 Bar (60 PSI).
