Sprinkler Valve

Use an electric anti-siphon valve for your automatic sprinkler system. A sprinkler valve is specifically designed for ease of installation, adjustment and service. It can be operated automatically by any sprinkler control timer as well as manually at the valve. A sprinkler valve not only controls the flow of water to your sprinklers but also prevents contaminants from siphoning back into the freshwater supply after the sprinklers are shut off. This important safety feature, called an Atmospheric Vacuum Breaker (AVB), must be correctly installed to the function properly. Therefore, before starting the valve installation, read through the instructions.

Installation Requirements
1. The valve must be installed at least 6" above the highest sprinkler it controls, or according to local codes.
2. No additional valves other than drain valves should be connected between the valve and the sprinklers.
3. The valve outlet must not be subject to backpressure at any time.
4. The valve must be installed in an accessible outdoor area in a vertical and level position.
5. The valve must not operate continuously for more than 12 hours.
6. Always check local codes for specific regulations regarding the installation of under-ground sprinkler systems.

Specifications for fitting a sprinkler valve:
1. A pressure regulator must be installed upstream of the valve if the static water pressure exceeds 80 PSI.
2. Installing a manual shut-off valve between the water source and the sprinkler valves is recommended. This will enable the sprinkler system to be easily serviced and/ or drained for winterization without interrupting the household water supply.
3. Use only Teflon tapes on threaded valve connections.
4. Flush water supply line thoroughly before installing the valves. Sand and dirt in the line can damage the valve and prevent the valve from operating properly.
5. If installing two or more valves together provide a minimum clearance of 4" between valves to enable removal or tightening of valve if necessary.
6. After allowing pipe cement to secure thoroughly, apply water pressure to valves and check for leaks at all fittings.
7. To manually test valve operation, turn the solenoid slowly by hand counterclockwise 1/2turn. The valve should open within 5 seconds. To close the valve, turn the solenoid clockwise until snug.
8. To reset to a higher flow rate, turn the flow control counterclockwise.
9. Select a cable with at least one wire for each valve plus one wire to serve as a return common for all valves.
10. For future expansion of the sprinkler system, use a cable with extra wires to accommodate additional valves.
