Spiral Spray Nozzles

The spiral nozzle, sometimes called helix, pigtail, or corkscrew, disperses liquid as it shears along the turns of the spiral. There are no internal parts, but instead it has an external spiral vane.

In 1950, the spiral nozzle was the first of many spray nozzle innovations from BETE. We are still the leaders in spray nozzle design and manufacturing. Our years of experience can provide optimal results for your business operation.

What BETE nozzles are considered Spiral?

Spiral Nozzle Design Specifications and Frequently Asked Questions

The external spiral or “pigtail” shape distinguishes this nozzle type from others.

The spray angles and coverage depend on the type of cone:

  • 60, 90, 120 (Full and Hollow Cone)
  • 150, 170 degrees (Full Cone only)
  • 180 degrees (Hollow Cone only)

Spiral nozzles produce fine atomization, the smallest droplets coming from a non-misting, direct pressure nozzle.

  • If you desire a small drop size, the spiral design can increase process efficiency (chemical, environmental, etc.)
  • If you need more coverage or increased angle formation at higher pressures (vs. whirl style), spiral nozzles provide excellent results.
  • N series is an UL/FM approved spiral and similar to deflector-type fire nozzles for fire protection systems.

BETE engineers excel at selecting nozzles from our comprehensive inventory to develop a custom solution for your application — including your specific operating pressures, spray coverage, spray angles and droplet size requirements.
