Full cone spray nozzles distribute liquid across a filled circular or square impact area. They are commonly considered when a process needs broad wetting, rinsing, cooling, quenching, dust control or chemical distribution over a target. Selection should be based on the required flow at the pressure available at the nozzle—not on spray pattern name alone.
Choose a Full Cone Nozzle by Spray Requirement
| Requirement | Recommended starting point | What to verify |
|---|---|---|
| Compact coverage or greater spray reach | BBG narrow-angle full cone nozzle | Flow, pressure, target distance, connection and material |
| Broad coverage at a shorter distance | Wide-angle full cone nozzle | Actual spray width, installation height and pattern stability |
| Square coverage or multi-nozzle header layout | BB square full cone nozzle | Orientation, overlap, edge coverage and header spacing |
Engineering Checks Before Selection
- Flow and pressure: use the model performance table for water and confirm the actual pressure available at the nozzle inlet.
- Spray angle and distance: calculate the theoretical footprint, then allow for gravity, pressure, liquid properties and installation conditions.
- Liquid properties: viscosity, specific gravity, temperature, suspended solids and chemical compatibility can change performance or material choice.
- Free passage and filtration: compare the liquid cleanliness and particle size with the selected model and the upstream filtration plan.
- Connection and orientation: specify NPT or BSPT, male or female connection, mounting direction and available installation space.
- Material: select stainless steel or brass only after checking compatibility with the liquid and operating environment.
Full Cone Nozzle Applications
Full cone spray is used where liquid is needed throughout the target area rather than mainly around the perimeter. Typical engineering evaluations include stationary washing, cooling and quenching, dust control, process-water distribution and chemical spraying. The correct model still depends on flow, pressure, target geometry, liquid condition and maintenance access.
For a detailed selection method, see the full cone spray nozzle engineering guide. For application and verification work, use the cooling and quenching checklist and the spray distribution test method.
Request a Technical Selection Review
For an efficient review, send the required flow per nozzle, available pressure at the nozzle, target size and distance, liquid composition and temperature, preferred connection, material requirement and quantity. Jeltecn is a registered brand of Melinco Precision Technology Co., Ltd. Product suitability should be confirmed against the final operating conditions and the selected model data.
