Catalog excerpts

The XA nozzle system uses the energy in compressed air to produce highly atomized sprays at low flow rates. There are many interchangeable components that can be assembled to achieve a variety of spraying objectives. ANNULAR AREA AIR FEED LIQUID FEED External Mix Setups may be used with liquids having a viscosity above 200 centipoise and for abrasive sus pensions. BETE Applications Engineering can provide guidance for spraying high viscosity liquids. TO ORDER: specify pipe size, body style, spray set-up #, hardware and mounting assemblies, and material. See page 74. SPRAY SET-UPS XA nozzles produce eight distinctly different types of sprays, depending AIR CAP FLUID CAP on which interchangeable air and Cutaway View: Internal Mix Set-up fluid caps are selected. The spray type and flow rate are determined by the ”setup”—a specific combination External Mix Set-ups The air and liquid streams exit the of one air cap and one fluid cap. nozzle independently and are com Internal Mix Set-ups bined and mixed outside of the nozzle. Liquid and air streams meet within Because there is no connection between the air and liquid lines within the the nozzle and are mixed together nozzle, the air and liquid flow rates can and expelled through the same ori be controlled independently, allowing fice(s). This internal mixing means precise metering of the liquid. The the streams are not independent; a change in air flow will affect the liq atomization can be controlled by uid flow.

LIQUID FEED LIQUID ORIFICE Cutaway View: External Mix Set-up Siphon Set-ups Internal and External Mix Setups require the liquid to be supplied to the nozzle under pressure from a municipal water supply, pump, or pressure vessel. Siphon Setups use the flow of compressed air within the nozzle to siphon liquid from a container. Siphon Setups are frequently used for spraying additives from a container without the use of a pump. They provide the D. Clean-out/Shut-off Bold letters (A, B, C, D, E, F) refer to hardware assemblies shown on

XA Components & Options must be used when the air cylinder operates at a different pressure from the atomizing air or where the atomi zing air is supplied below 30 PSI. NOTE: The XA00 Square and XA03 Bodies used for nonautomatic operation can also be used, with hardware assem blies E or F, for automatic operation. Special design features allow field upgrading to automatic operation. The XA10 and XA11 Bodies have a built in airoperated cylinder. The integral cylinder provides a smaller profile for use where space is limited. Hardware Assemblies for Automatic Operation E. AirOperated...

TO ORDER: specify pipe size, body style, spray set-up #, hardware and mounting assemblies, and material. See page 74. SPRAY EXTENSIONS The spray setup can be moved away from the nozzle body by using optional 6” or 12” extensions. These allow the spray to be moved closer to the target while keeping the nozzle body and associated piping at a distance. MOUNTING HARDWARE In many XA installations the nozzle is supported by the rigid metal pipe that supplies air or liquid. There are several components which can provide support for the XA Bodies when it isn’t appropriate to suspend the nozzle...
