Toro P220 SERIES User manual

Introduction
Built on proven technologies and components, the ToroP 220 Series plastic
valves are tough, have excellent performance and are extremely reliable.
Aself-cleaning metering system and 220 PSI rating assures years of
trouble-free performance.
In commercial installations, it is advantageous to install the valves in a
valve box. This enables the valve to be located, accessed and maintained
easily. The use of clean aggregate in the the bottom of the box, and
keeping valve box locations away from structures, potential hardscaping
features (such as sidewalks) and large planting locations is recommended.
Additionally, valve box locations generally should be in shrub beds and at
right angles to structure locations. If the valves are installed below grade
without a valve box, access to the top of the valve should be provided using
a section of 4" PVC pipe and a Toro Valve Cover (Part No. 850-00) installed
directly over each valve.

Installation Guidelines
•Note the flow direction arrow in the side of the valve body and install accordingly.
•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.
Valve Operation and Adjustment
Flow Control
The flow control is used to reduce the flow and pressure to valve outlet. By turning the control handle clockwise, the flow will
gradually be reduced zero.
•For valve models without EZReg, adjust the flow control as necessary for optimum sprinkler performance.
•For valve models with EZReg, the flow control should remain in the fully open position. Use only for emergency shut off.
Manual Bleed Knob
The manual bleed knob is used to manually operate the valve. Turning the knob counterclockwise 2–3 turns allows water to
bleed downstream from the diaphragm chamber, relieving pressure from the top of the diaphragm which allows the valve to
open. Turning the bleed knob clockwise until finger tight, shuts off the discharge enabling pressure to build within the
diaphragm chamber, causing the valve to close.
EZReg (pressure regulated models only)
An accurate, adjustable dial coupled with a forward-flow valve design allows the 220 series valve with EZReg to regulate
downstream water pressure with precision. It can regulate accurately down to 5 GPM flow (1" model) and only requires 10 PSI
differential pressure to operate.The EZReg will operate during powered and manual valve operation.
To adjust, remove the cover from the regulator dial. Turn the dial until the pointer is on the desired downstream pressure:
5–30 PSI (EZR-30) or 5–100 PSI (EZR-100).
Note: Due to the micro-adjustment feature of the EZReg, the dial requires several complete revolutions to move the pointer
from the minimum to the maximum adjustment settings.
Operate the valve (electrically or manually). Check the flow control to confirm that it is in the fully open position.Adjust the
regulator dial if necessary for optimum sprinkler operation.
To confirm 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 EZReg
dial as necessary for the desired pressure.
Note: The valve will remain operational if removal of the EZReg assembly is required.
