Servo
A ball vale or buttery valve that is driven by an electric motor gearbox and
the valve is installed in the tank return line.
NOTE:
DICKEY-john Servo valves

100 Hz.
DRIVE FREQUENCY
Specifies the frequency for the proportional valve installed. The
recommended setting for this option should be specified from the valve
manufacturer.
FILTER
The amount of filtering applied to the frequency feedback of the control
channel.
IMPORTANT: It is NOT recommended that the Filter be altered. Any
adjustments could result in the channel not operating
properly. If adjustments are made a valve calibration
must be performed.
NOTE:
The correct number of pulses
generated for one revolution
must be determined for sensors
other than DICKEY-john.

standard DICKEY-john application rate sensor is used, the value should be
set to 360.0.

turns in relation to one revolution the final output shaft turns.
