S elec tion Guide This section describes some of the questions to be considered when selecting spray nozzles. In addition, answers for uncomplicated situations are provided where possible. In some applications, because of the large number of variables involved, accurate answers are not always possible except through actual testing or simulation. Our technical staff, however, may be able to lend assistance in their areas of expertise. Please feel free to give us a call. WHAT S P RAY NOZZLE CONS TRUCTION D O I REQUIRE?

WHAT TYP E OF CONNECTION D O I REQUIRE? BEX spray nozzles are available in many different connection styles. The most common connection types depend on the industry where the nozzles are being used. Generally, however, the most common connection is the standard tapered, or NPT, pipe thread. The outside diameters of NPT threads are Other common connections include the quick disconnect style, or BEX Zip-Tip®, which is a bayonette style of connection whereby a tip is inserted into a threaded body, and the BEX clip-on K-Ball® series, which is a style of nozzle which connects to a pipe by means...

WHAT FACTORS WILL AFFECT MY SPRAY CHARACTERISTICS? When the conditions controlling spray nozzle performance change, the spray characteristics may change. This section lists conditions which may vary, and how those conditions may affect the spray characteristics. PRESSURE: The flow rate of a liquid is proportional to the square root of the pressure difference between the pressure liquid and external (usually atmospheric) conditions, thus higher pressure generally results in finer spray atomization, greater spray impact, and greater spraying distance. VISCOSITY: Spraying liquids with higher...

Theoretical coverage (W) at various distances (D) from the nozzle INCLUDED SPRAY ANGLE Spray coverages shown in Table 1 are based on straight sided spray patterns. At low pressures the sides may curve in, as shown at the right, because of the acceleration due to gravity. To find the width of a spray (W) at any distance (D), multiply the W/D ratio by the distance.

P r eventing Nozzle P r oblem s Monitor Nozzle Performance Flow rate Flow rate can be measured by connecting a flowmeter in series with the nozzle, or collecting the output from the nozzle in a container of known volume over a measured period of time. If the flow rate is higher than the nozzle specifications then it is possible that the orifice has partially corroded or eroded away. If the flow rate is lower than specified then the nozzle could be clogged or caked. Such problems are often accompanied by a change in spray pattern or distribution. Pressure A decrease in your system pressure...

Com m on Caus es of Nozzle P r oblem s Corrosion The nozzle degrades due to chemical reactions between the nozzle material and the chemicals in the process. Temperature If nozzles are subjected to temperatures greater than recommended then physical damage can occur. Erosion/Wear As fluid passes through the orifice and internal passages of the nozzle the critical surfaces can become worn, thereby creating a poor spray. Clogging Many chemical compounds and particles larger than the maximum free passage of the nozzle will clog the nozzle. Caking Many chemicals will slowly build up on the...
