maintained. The pressure points shall be
graphically illustrated in PSI and kg/cm2.
The pilot valve assembly shall include a
pressure-regulation
continuously monitors the operating
pressure inside the sprinkler body while
in operation, making the necessary
adjustments to ensure the desired and set
regulation pressure is maintained. The
pilot valve assembly shall incorporate a
manual control feature that is accessible
from the top and allows the sprinkler to
be manually selected "ON", "OFF", or
placed in the "AUTO" position awaiting
commands from the control device. The
manual selector shall be red in color for
enhanced visibility.
The pilot valve
assembly shall be stamped with the
manufactured date code and shall be
retained in the compartment with a single
stainless-steel screw.
The sprinkler shall be of a pop-up design

a discharge rate of ___ gallons per minute.
Water distribution shall be via three nozzles
mounted in a 2¼"-diameter (57mm) plastic
nozzle turret. The three nozzles shall be

The sprinkler shall include a nozzle base
clutching feature that allows the user to
rotate the nozzle base in either direction, wet

operation to allow for spot watering.
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
designed to provide smooth valve closure in

ABS– a corrosion-proof, impact-resistant,
UV-resistant, heavy-duty, engineering-grade
plastic material. The cap and nozzle base
shall incorporate a pull-up feature that
provides improved serviceability of nozzles

The sprinkler shall have two
plastic filter screens – a top-serviceable
coarse rock screen in the body inlet sized to
prevent larger foreign material from entering
the body, and a finer screen threaded into
the riser, sized to prevent foreign material
from clogging the nozzle.
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 is sealed by a durable, over-molded
urethane ring on the seal retainer. Sprinkler
