Installation and Operating Instructions
Introduction
e P220G Series valves are available in two operation and
two activation types.
Operation
• P220G is intended for golf and commercial applications with
normal water conditions.
• P220GS “Scrubber Valve” models are intended for applications with dirty
water conditions. ese models include Toro’s patented “ACT” system
with a rotating turbine that continuously cleans the stainless steel screen
during operation.

Activation
AC powered - For satellite systems, the 24 VAC Spike Guard solenoid
P220 (G,S)
2”
provides 20,000 volt lightning protection to minimize down time and service
costs. Moreover, it draws less than half the wattage of traditional solenoids for
a lower long-term cost of ownership.
DC powered - For GDC 2-wire systems, a DC-latching solenoid reduces the
system wire load to lower initial system cost. It is activated by a momentary
pulse “on” and “o”, meaning there is no continuous power draw, providing a
lower long-term cost of ownership.
e P220G EZReg pressure regulator adjusts easily with the micro-adjust dial
and indicator to provided constant downstream pressure between 5-100 psi (,34-6,9 bar).
Note: e P220G valve should be installed below grade in a valve box or vault (see page 2) to provide service access and vandal
resistance. e valve installation site should be readily accessible by grounds maintenance personnel and well clear of hardscape
features, cart paths, and foot trac areas.

Installation
• Note the ow direction arrow in the side of the
valve body and install accordingly.
• e valve can be installed at any angle without
aecting operation.
• Use direct-burial irrigation control wire for
connection from the controller to valves.
• Leave a 12” (305 mm) wire expansion loop at
each valve location on long-run wire lengths.
• Waterproof wire splice connectors are
absolutely essential for proper electric control
system operation. Follow the installation
instructions provided by the connector
manufacturer for optimum performance.
* Distances specied under the following
conditions: minimum voltage: 20 VAC, amperage:
0.12A, operating pressure: 150 psi (10,3 bar).

Valve Adjustment
Flow Control
e ow control is used to reduce the ow and pressure to
valve outlet. By turning the
ow control handle clockwise,
the ow will be gradually
reduced to zero.
Note: e ow control
should remain in the fully
open position. Use only for
emergency shut o or for valve
zone ne-tuning.
Internal Bleed Knob Downstream pressure
regulation maintained
e internal manual bleed
system is used to manually
operate the valve. Turning
the internal bleed knob
(located beneath the solenoid)
counterclockwise allows water
to bleed downstream from the diaphragm chamber. Internal
pressure is relieved from the top of the diaphragm, allowing
the valve to open. Turning the bleed knob clockwise until
tight shuts o the discharge enabling pressure to build within
the diaphragm chamber, causing the valve to close.
External Manual Bleed Knob (ush mode)
e external manual bleed knob, located on top of the ow
control handle, is used for system ushing. Turning this knob
counterclockwise allows water in the diaphragm chamber to
vent to atmosphere, creating maximum opening power and
debris ushing action. is operation bypasses the regulator
and opens the valve fully, regardless of regulator setting. In
addition, the metering rod (attached to the external bleed
knob) can be easily removed for cleaning as necessary.
EZReg Adjustment
An accurate, adjustable dial, coupled with a forward-ow
valve design, allows the P220
series valve with EZReg to
regulate downstream water
pressure with precision.
It’s easy and simple to use
and requires only 10 PSI
dierential pressure to operate.
e EZReg will operate
during powered and manual
valve operation using internal
manual bleed.
To adjust the downstream
pressure, remove the cover
from the regulator dial, then
turn the dial until the pointer
is on the desired pressure of
5-100 PSI (EZR-100).
Note: Due to the microadjustment feature of the EZReg, the dial requires 10
revolutions for complete regulation range.
Operate the valve (electrically or manually). Check the
ow control to conrm that it is in the fully open position.
Adjust the regulator dial if necessary for optimum sprinkler
operation.
To conrm the downstream pressure using a pressure gauge,
remove the cap from the Schrader-type valve located directly
below the EZReg. Attach a Toro pressure gauge (Model 995-
51) to the Schrader-type valve for a direct reading. Adjust the
EZReg dial as necessary for the desired pressure.
Note: e valve will remain watertight in the closed position
if removal of the EZReg assembly is required.
