Figure 7.2: Typical Four Branch Distribution System Flow Schematic
NOTE: Some components shown here are optional. Not all systems
contain all components. Most valves have the option of being either
pneumatically or manually controlled. In certain cases, the pressure
transducers may be replaced with another type of pressure monitor
(i.e. switch, gage, transmitter). Valve numbering is repeated for
Branch 5 and 6 of a six branch Distribution System or Branch 5
through 8 of an eight branch Distribution System.
V1 Process In Emergency Shutoff Valve Optional pneumatic
control valve isolates process gas supply from cabinet to the
Distribution System.
V2 High Pressure Process Valve [branch 1-4 (A-D)]
Pneumatic control valve permits flow from Branch 1 through 4
piping.
