The Rainbird 10VAN variable arc adjustable sinkler nodule 10 pack is perfect for all standard and irregularlyshaped turf and shrub areas. These nozzles are adjustable from 10 to 12 feet and fits all Rainbird say heads and shrub adapters. These arc nozzles feature UV resistant plastic and a stainless steel adjustment screw to increase the life of this oduct.Selecting the correct nozzle is one of the most crucial, yet overlooked, in irrigation system design. Choosing the correct nozzle, whether it's for a say head or a rotor, is easy if you take the time to study the nozzle charts in a manufacturer's oduct or online catalog and select one that best suits your needs; irrigation equipment manufacturers have put a tremendous amount of effort into developing nozzles to fit almost every application: For slopes and compacted soils, select a nozzle with a lower ecipitation rate. For windy areas, select a nozzle with a low nozzle outlet trajectory. To achieve even water distribution without having to separate partcircle from fullcircle sinklers, select a nozzle set that features a matched ecipitation rate. Another way to ensure uniform watering, if you're working with say heads, is to select nozzles that have an undercut nozzle. These nozzles have an second, undercut orifice for watering closer to the head. For flexibility with say heads, select a nozzle with an adjustable or variable arc. Because nozzles are designed to work within a wide range of essures, it is important to ensure you have the correct essure at the base of the nozzle.Too much essure, as is commonly the situation with say heads, will result in misting. Misting creates a reduction in the of throw and you may experience uneven coverage, and cause wet and dry spots. To correct this, several manufacturers offer devices that can be installed at the nozzle or are integrated in the sinkler, such as the Rainbird S Series.
