without failure. It shall also have a nickel-
plated core to provide additional corrosion-
resistance in potable and non-potable water
applications.
DC Latching Solenoid
The DC latching solenoid shall be activated
by a momentary low-voltage pulse that
moves the plunger from the “OFF” to the
“ON” position where it is maintained by a
permanent magnet in the solenoid. To
deactivate, a second momentary low-volt
pulse is applied to move the plunger from
the “ON” position to the “OFF” position.
This activation type is generally used with a
GDC module that is remotely located.
Integrated GDC Module
The Integrated GDC Module activation
type incorporates the GDC module attached
to the outside of the sprinkler body and
includes a DC latching solenoid for
activation of the control valve. The DC
latching solenoid shall be activated by the
Integrated GDC module with a momentary
low voltage pulse that moves the plunger
from the “OFF” position to the “ON”
position where it is maintained by a
permanent magnet in the solenoid. To
deactivate, a second momentary low-volt
pulse is applied to move the plunger from
the “ON” position to the “OFF” position.
The internal valve assembly shall be a
piston-type that vents to the atmosphere,
providing valve friction loss of less than 5
psi (0,34 Bar). The sprinkler shall be

Recommended Installation Procedures
The FLX55-6 sprinkler is designed
specifically for turf areas requiring _____
coverage. These products offer the most
economical method of irrigation where flows
and system pressures are available to support
a greater radius.
The FLX55-6 sprinklers should be
specified for installation on a Toro swing
joint. The swing joint should be specified as
a triple-swing type, allowing movement up,
down, laterally and at an angle-to-grade. The
sprinkler should be installed with the body
cover at grade.
Individual sprinkler head control is
accomplished using a single FLX55-6 valve-
in-head sprinkler per controller station. Use
of the valve-in-head model will allow
individual station control, and is particularly
useful for irrigating distinct turf regions at
unique application rates.
FLX55-6 sprinklers are engineered to
provide a smooth, consistent curtain of
water across the arc, with provision made for
head-to-head coverage. For proper spacing,
ensure that system design and installation
accounts for prevailing wind conditions and
body cover angle-to-grade.
It is recommended that sprinklers are
installed 2” (5cm) from hardscaping and 6”-
12” (15,2-30,5cm) from buildings or other
vertical impediments to allow for normal
maintenance procedures and to minimize
overspray on buildings. Where possible,
sprinkler heads should be installed in a
manner that will minimize nozzle stream
contact with trees, controller enclosures,
shrubbery or other obstructions.
