Full Cone Spray Nozzles

The most commonly used nozzle type in industry is the Full Cone nozzle. The nozzle emits spray in a conical shape by dispersing liquid over the cone’s interior. When the spray meets with a surface, a circle of spray is created with liquid present throughout.

What BETE nozzle series and types produce this spray pattern?

How is this spray pattern achieved through nozzle design?

  • WL, MPL, MP, CW, SC, NC, NCS, NCK, NCFL and TC series: for these Full Cone nozzles, the pattern is achieved by way of an internal vane. The water passes through this vane, and because of the angular passageways, the liquid starts to spin. The spinning creates a centrifugal force exerted upon the geometry of the exit creating the spray pattern.
  • WTZ and TSC: for these Tangential Full Cone nozzles, the spray pattern is achieved by introducing the liquid into the body of the nozzle by way of a slight angle so the liquid swirls around the body cavity before exiting the orifice. In order to create a full cone version of the tangential set up, one wall of the nozzle with fins disrupts the swirling of the liquid and directs it toward the center of the orifice.

Operating Specifications & Frequently Asked Questions for Full Cone Nozzles

Full Cone nozzles typically offer the most even distribution of droplets across the spray pattern.

The Full Cone Nozzles listed above typically create larger droplets as compared to similar Spiral Type nozzles.

Typical operating pressures are on the low end, mostly between 3-80 psi delta P (depending on nozzle series and rating).

Flow rates depend on the type of application you have.

  • If you are looking for even distribution over a packed bed, a Full Cone nozzle pattern provides great coverage results.
  • Rain Simulation and Foam Control applications provide even distribution over specific surface areas using Full Cone nozzles.
  • The 2 MaxiPass nozzles are designed with an S vane for larger free passage while the other Full Cone series utilize a disc that have smaller areas that could trap particulates that are in the water.
