BETE Abrasion and Clog-Resistant Pigtail Spray Nozzles
The BETE STXP is one of the original spiral nozzles. It has a high discharge velocity and high energy efficiency. BETE STXP Spray Nozzles are clog-resistant, with no internal parts.
The spray pattern is formed by impacting the fluid onto a protruding helix after exit form the spray orifice. The liquid then shears off the helix, breaking into droplets and forming the spray pattern. The spirals actually produce concentric rings of multiple hollow cone spray patterns with a less uniform liquid distribution between the cones to produce an approximate full cone pattern. By varying the geometry of the helix, however, a hollow cone pattern can be achieved. Spiral nozzles will, for any given flow rate and pressure, produce a full cone spray with the smallest droplet size for any direct pressure nozzles.

How Spray Pattern for the BETE STXP Spiral Nozzle is Achieved
The spray pattern of the spiral nozzle is formed by the fluid shearing along with the turns of the spiral, which produce multiple concentric cones. These cones form 2 to 3 bands of relatively coarse droplets surrounded by wider bands of relatively fine droplets.
