This valve from Rain Bird controls water flow to individual irrigation zones. It opens and closes on command from the irrigation controller, directing pressurized water to the sprinklers in its assigned zone. Proper valve selection ensures reliable operation and prevents water hammer.
Key specifications for valve selection: the maximum flow capacity must exceed the total demand of all sprinklers in the zone, and the inlet size must match your mainline pipe diameter. Operating pressure range should align with your water supply characteristics.
Install this valve at the beginning of each irrigation zone, downstream of the mainline and backflow preventer. Size the valve to comfortably handle the total flow demand of all sprinklers in the zone — a safety margin of at least 10–15% above peak demand is recommended.
