TeeJet 844 Sprayer Control - Manual (Page 7)

PRESSURE REGULATOR IN
THROTTLING MODE
In large flow situations, the pressure regulating valve, as shown in Figures 8 and
8A, can be located in the supply line before the boom control valves. If you
choose this location, the 844 will need to be properly programmed to reverse the
polarity of the valve. This step can be found in the System Setup instructions on
page 21. When in throttling mode, the valve should open when the key is
depressed, and close when the key is depressed. Be sure to check this
before plumbing the valve into the system.
