The adjustable spherical series spherical nozzles are widely used in spray pre-treatment processes. They have two connection methods: clip type and thread type (internal thread and external thread). Clamp-type nozzles are fixed on the header with spring clips, while thread-type nozzles use threaded connections. The adjustable spherical nozzle is composed of five major components: base, cap, sealing ring, spring clip and nozzle; this combined nozzle system can provide three different spray modes: fan shape, hollow cone shape, and solid cone shape. Through the combination of threaded balls, quick-release balls and various common traditional nozzles, the range of adjustable spherical nozzles can be further expanded to meet diverse application needs.
