Manual Operation (Figure 4)
• Bleed Screw (external bleed): To open the valve, turn the Bleed Screw counterclockwise one full turn or until water begins discharging from the port. Note: Removing the bleed screw is not required but
can be removed to help flush debris from the upper diaphragm area.
To close the valve, turn the bleed screw clockwise until it stops. Do not over-tighten!
•Bleed Handle (internal bleed): To open the valve, move the Bleed Handle counterclockwise to the stop. To close the valve, move the handle clockwise until resistance is 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 maximum 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.

1" In-line Valve Models 53707 and 53709
- 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 
53709 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. |
53707 |
|
|
|
|
Important: These valves do not provide backflow protection. |
53709 |
|
A backflow prevention device installed between the 1" in-line |
|
|
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.

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.
Step 2- The instructions and illustrations on the next page provide the most commonly recommended methods of installing in-line valves in a manifold arrangement. Use the appropriate step-by-step instruction for the valve model being installed.
