In commercial installations, it is
advantageous to mount valves in a valve
box. Logically, if mounted in valve
boxes, they can be located, accessed
and maintained easily. Instructions

and keeping valve box locations away
from structures, potential hardscaping
features (such as sidewalks) and large
planting locations. Additionally, valve
box locations generally should be in
shrub beds and at right angles to
structure locations. Valves can be
below grade but, even so, should
specify the use of 4" PVC pipe to the
valve bonnet and a Toro valve cover
(Part No. 850-00).
The pressure-regulating model gives
you a specifying choice in cases where
you must reduce a high available
pressure, where you are running
downhill or where you must isolate a
lateral at a lower pressure than the main
line. The pressure-regulating model
maintains a constant downstream
pressure, regardless of fluctuating
upstream pressure and flow conditions
through the valve.
Electric control valve instructions
should specify direct-burial wire,
utilizing different colors for hot hook-up
to each remote location and one color
for the common wire to all valves.
Watertight splice connections are
absolutely essential for proper valve
operation and should be covered with
in-depth instructions. Expansion loops
at each valve location on long-run wire
lengths generally are a good idea.

Pressure Regulating Electric Models:
The pressure regulator, EZReg, shall
be of dial design to permit visual setting
of pressure with or without the valve
being operated or the use of a pressure
gauge. The regulator shall be of a
screw-in type and shall regulate
precisely over a 5-100 PSI range with
maximum inlet pressure of 220 PSI. The
regulator shall maintain the set pressure
within ± 3 PSI (with a 10 PSI differential
between inlet and outlet).

The valve shall have a plastic
solenoid, which is fully encapsulated
and have a captured hex plunger and
spring. The solenoid will have a
removable retainer for servicing of the
spring and plunger. The plunger shall
be on a stainless-steel solenoid seat for
longer life. The 24 V a.c. solenoid shall
open with a 22.5 V a.c. minimum at
220
PSI. At 24 V a.c. average inrush,
current shall not exceed 0.40 amps.
Average holding current shall not
exceed 0.20 amps.
