Installation Procedures
The valve seat seal shall be constructed
of fabric-reinforced natural rubber.
The electric valve assembly shall
incorporate a 100-mesh stainless steel
screen for the control water; preventing
entry of foreign materials into the pilot
valve assembly. Rotation shall be
accomplished by a water-lubricated gear
drive. The drive assembly shall be
driven by a spring loaded, poppet-type,
variable stator, sized to provide three-
minute, full-circle rotation speeds
throughout the pressure range. The
drive and stator assemblies shall be
constructed of non-corrosive plastic and
stainless steel components.
The body and cap of the sprinkler
shall be injection molded from ABS:
a corrosion-proof, impact-resistant,
UV-resistant, heavy-duty engineering-
grade plastic material. The body shall
incorporate an indestructible, molded-in
stainless steel valve seat, capable of
withstanding debris contamination with
no permanent damage. The valve seat
shall never require servicing. The cap
and nozzle base shall incorporate a
pull-up feature that provides improved
serviceability of the nozzles and riser
assembly. The sprinkler shall have two
plastic filter screens: a top-serviceable
coarse rock screen in the body inlet,
sized to prevent entry of larger foreign
material from entering the body, and a
finer screen threaded into the riser; sized
to prevent foreign material from
The sprinkler cap shall indicate model
designation, main nozzle number and
manufacturing date code. The exposed
body flange shall display warnings to
ensure safe operation.
The sprinkler shall be available in
three body styles/activation types as
follows:
Normally Open Valve-In-Head
The integrated hydraulic valve shall
be activated remotely by relieving
pressure to open and applying pressure
to close. The control connection shall be
The 835S Series 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 835S Series sprinklers should be
specified for installation on a 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 flange at grade.

polyethylene tubing and a push-on
tube retainer.
Individual sprinkler head control is
accomplished using a single 835S per
controller station. Use of the valve-
in-head sprinkler model will allow
individual station control, and is
particularly useful for irrigating in
distinct turf regions using unique
application rates.
Check-O-Matic
The integrated check valve shall be
capable of preventing low-head
drainage up to 37' (11,2m) of elevation
change. The check valve shall be
vented to atmosphere via the sprinkler
body bowl. The vent connection shall
be a brass fitting with

Check-O-Matic models are generally
found in block systems where one
valve is used to activate two or more
sprinklers. The spring-loaded check
valve function will prevent low-head

thereby helping to eliminate water

polyethylene tubing and a push-on

Electric Valve-In-Head
The sprinkler shall incorporate a low
wattage, surge protected, electrical
solenoid for activation of the integrated
control valve. The solenoid operator
shall be suitable for 24 VAC, 50/60 Hz
service with inrush of .12 A @ 50/60
Hz, and holding of .10 A @ 50/60 Hz.
The solenoid shall be capable of

withstanding lightning surges in excess
of 20,000 volts without damage.
835S Series 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
flange angle to grade.
All internal components shall be
serviceable from the top of the sprinkler
without disturbing the body installation.
The riser and internal valve assemblies
shall each be retained by a single snap
ring.
The sprinkler shall have a riser/body
seal assembly that regulates flushing
during pop-up and retraction, to clear
any debris from around the riser, and
a heavy-duty stainless steel spring, to
ensure positive retraction. The riser seals

on the seal retainer. Sprinkler flush rate
shall not exceed 5.0 GPM (18,9 LPM).
The sprinkler shall be capable of
Separate models shall be available with
low-wattage/high-surge performance,
capable of performing in non-potable
water applications, and with a DC-
latching solenoid for use in 2-wire
decoder systems. A manual selector
switch with On-Off-Auto positions shall
be provided and accessible above grade
with a special key. Pressure regulation
shall be factory preset and field-selectable
to 50, 65, 80 or 100 psi (3,5, 4,5, 5,5 or 6,9
Bar).
The sprinkler shall be developed and
manufactured by an ISO 9001-certified
facility. The sprinkler shall be model
number _______________________ and
shall be manufactured by The Toro
Company, Irrigation Division.
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, sprinklers should be
installed in a manner that will minimize
nozzle stream contact with trees,
identifying the use of effluent water on
the exposed cap of the sprinkler via
a lavender-colored cap assembly. A
patented insert shall also be available for
providing numeric values for yardage
marking.
