Connecting the Valve Wires (Figure 3)
Step 1- Route 18 AWG direct-burial sprinkler cable
from the timer to the valves.

Step 2- Using wire splice connectors, attach either
wire from each valve solenoid to the white cable
wire. This wire is designated as the valve “Common
Wire.” Connect the remaining wire from the sole-
noid to one of the color-coded wires.
Important: All wire splices must be insulated
with grease caps or similar waterproofing devices.
Step 3- At the timer, connect the control wires to
the numbered terminals in the desired operating
sequence and the valve common wire to the com-
mon terminal.
- Installation Guide -
The Toro 1" in-line electric valves are designed for use in
an automatic sprinkler system controlled by a 24 V a.c.
sprinkler system timer. The valves feature manual flow
control adjustable down to zero flow and manual
bleed controls which enable the valve to be operated
without the use of the timer. The 53707 valve is
designed for slip-fit pipe connections and model

features female-threaded inlet and outlet.
These valves are generally installed below grade,
grouped with other valves in a manifold arrange-
ment and housed in a protective valve box.

Step 4- Using the timer’s manual control feature,
test the operation of each valve.
Important: These valves do not provide backflow protection.

Manual Operation (Figure 4)
valve(s) and the water source point of connection is required in most areas to prevent
back-siphoning of contaminants through the sprinkler system into the potable water
supply. The Toro 1" Pressure Vacuum Breaker (PVB), model number 53300, is
specifically designed for this purpose. Before connecting your irrigation system to the
potable water supply, consult with your local water utility department for information
regarding backflow prevention requirements. Where local water pressure exceeds 70
psi, a presure regulator should be used. (See Uniform Plumbing Code, Sec. 1007[b].)
It is advisable to use a regulator with any automatic valve to assure long life as well as
uniform and controllable operation.

felt. Do not over-tighten!
•
Flow Control Adjustment: With the valve operating, use a small screwdriver to turn
the flow control screw clockwise to decrease flow or counterclockwise to increase flow.
Note: The flow control screw requires approximately seven turns to adjust from maxi-
mum to minimum flow.
Caution: Do not use the flow control to shut off the valve. Do not force the flow
control screw past the end of normal adjustment travel. Damage can occur.

Installation Procedure
Note: To ensure ease of installation and optimum valve performance, please read
through the following instructions completely before starting the installation procedure.
Step 1- Route 1" schedule 40 PVC pipe from the backflow preventer or system
shut-off device to the valve location. Flush the supply line thoroughly!
Caution: Dirt, rocks and debris entering the valve can damage the valve and/or
cause the valve to malfunction.
All implied warranties, including those of merchantability and fitness for use, are limited to the duration of this express warranty.
