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.
