2500 Series Valves
Installation Instruction
The Irritrol® 2500 Series is a classic example of value in design. Borrowing heavily from
the proven 205 Series valves, the 2500 host a full menu of enhancements including
a patented “oating metering system” for consistent performance in dirty water
applications and a rugged, double-beaded diaphragm for long-term performance with
no leakage. The 2500’s manual internal bleed enables the valve to be opened without
îšżlling the valve box with water. And servicing is made easy and efîšżcient with captured
screws. These are just some of the features that make the 2500 Series valve rugged for
a reason.
Features
• Patented “oating metering
system”
• High-ow, low friction loss design
combined with low-ow cabability
• Rugged, double-beaded EPDM
diaphragm
• Internal and external bleed
(ush mode)
• Full stainless steel metering
system
• Heavy-duty, corrosion and UV-
resistant PVC and stainless steel
construction
• Available in female NPT or slip
conîšżgurations
(no male pipe adapter required)
• Floating bleed tube allows thermal
expansion without affecting
performance.

Installation and Operating Instructions
Automatic in-line valve can be operated
either manually or electrically.
In areas where freezing conditions occur,
be sure to install a way to drain the
system before freezing weather arrives. To
do that, use a shut-off valve on the main
line feeding the sprinkler system. Shut off
the water supply then electrically operate
each valve for at least a few minutes
(dry run). This vents the upper cavity of
the valve and makes sure the valve is
completely drained.
Although the valve is rated to 150 psi, a
pressure regulator should be used where
local water pressure exceeds 80 psi. (See
Uniform Plumbing Code, Sec. 1007(b).)
We suggest using a pressure regulator
with any automatic valve to ensure long
life, uniform performance, and controlled
operation.
Step 1 - Flush line thoroughly before
installing valve. This valve is designed
with slip x slip inlet connections and glues
directly to 1” PVC pipe.
Step 2 - Use PVC pipe cement only. Glue
valve directly to 1” PVC pipe. No threading
is necessary.
Caution: Do not plug in the
transformer until all valves has been
connected.
Step 3 - For each location, run one
common wire that will serve all the valves
at that location. Wiring can be buried
underground under the pipes. For runs
under 800 feet, use 18 gauge direct burial
irrigation wire. For runs over 800 feet, use
14 gauge direct burial irrigation wire.
Each valve has two wires. One will
be connected as the “common” wire.
Splice the common wire from each valve
together to make a single wire. Connect it
to the timer. Be sure all splices are joined
with wire nuts. Again, make sure all wire
splices are waterproof.
The remaining wire on each valve is the
“lead” wire. Connect each lead wire to the
timer at the numbered terminals, one lead
wire per terminal.
Step 4 - Plug in your timer. Be sure you
use only a timer with a Class 2, 24V
transformer.
Step 5 - Turn water supply on.
Note: The valve will remain on until the
air in the upper cavity is bled off. To
do that, turn the manual bleed screw
counterclockwise until water squirts out.
Then either tighten the bleed screw or
electrically run the valve for about thirty
seconds. The valve will shut off within a
minute.
Notice: This is not a backow prevention
valve. In needs to be installed in
conjunction with an approved backow
prevention device. Check state and local
plumbing codes prior to installation.
• In commercial installations, it is
advantageous to install the valves in
a valve box. This enables the valve
to be easily located, accessed, and
maintained.
• Partially ll the bottom of the valve
box with clean aggregate to faciliate
drainage.
• Locate the valve box away from
structures, hardscape features (such
as sidewalks), and large planting
locations.
• Locate the valve box in shrub beds and
at right angles to structure locations.
• If valves are installed below grade
without
a valve box, access to the top
of the valve should be provided by
using a section of 4” PVC pipe and a
valve cover installed directly over each
valve.
Using pipe dope on valve
connections can cause thread
damage and failure of the valve
body.
Use only PTFE tape or pipe thread
sealant.
• The valve can be installed at any angle
without affecting operation.
• Use direct-burial wire, utilizing different
color codes for each station control
wire and one color for the common
wire to all valves.
• Waterproof wire splice connectors are
absolutely essential for proper electric
control system operation.
Follow the installation instructions
provided with the connectors for
optimum waterproof splice protection.
• Leaving a wire expansion loop at each
valve location on long-run wire lengths
is recommended.
