Spray nozzles are devices used to control the direction and flow of liquids, often in the form of a fine mist or spray. They are commonly found in various applications, including agriculture, cleaning, and industrial processes. By adjusting the nozzle design, users can achieve different spray patterns, droplet sizes, and flow rates to suit specific needs. These nozzles can be made from various materials, such as plastic or metal, depending on the intended use and the type of liquid being sprayed. Proper selection and maintenance of spray nozzles are essential for efficiency and effectiveness in their applications.
