Valve

Valve Type
Select the type of control valve used to control the selected product during a job.
Note:
If ‘PWM’ or ‘PWM Close’ is selected as the valve type, a button labeled ‘Modify PWM Settings’ will
be displayed on the calibration screen.
Valve Cal
Note:
If the dual loop control feature is enabled, the valve cal value will be replaced by the flow cal value.
The valve cal value helps the field computer adjust the valve control response for slight differences between
control valves and is required for product control. Raven Industries recommends the following calibration
values for initial system setup.
These values are good starting points and will generally yield adequate results, however, the valve cal should
be refined for the individual control valves installed on the specific machine. See
Valve Cal section on
page 194, for information on the components of the valve cal setting or on tuning the valve cal value.
