The Jeltecn BBG narrow angle full cone nozzle produces a filled, concentrated spray pattern for applications that require longer reach or a smaller footprint. This BBG narrow angle full cone nozzle series is selected by the required flow, pressure available at the nozzle, target distance, liquid condition, connection and material.

The values above summarize the product family. They are not the performance of one individual nozzle. Confirm the exact model row before ordering, and request review when the liquid differs materially from water.
When to Choose a Narrow-Angle Full Cone
- The nozzle must reach a target farther from the mounting point.
- The process needs a compact filled footprint rather than broad near-field coverage.
- Available installation space limits the spray envelope.
- Flow and pressure can be maintained at the selected nozzle position.
Selection Checks
- Define the target size and nozzle-to-target distance.
- Specify flow per nozzle and total system flow.
- Measure pressure at the nozzle, not only at the pump.
- Select the model from the published water table.
- Review the liquid temperature, viscosity, specific gravity and solids.
- Confirm material and thread standard.
- Verify the installed pattern under representative conditions.
Typical Applications for the BBG Narrow-Angle Full Cone Nozzle
The BBG narrow angle full cone nozzle is commonly specified where a compact, uniform spray is required at extended throw distances. Typical duties include tank interior washing through a small entry port, dust suppression along conveyor transfer points, quenching of hot stock in confined process lines, and cooling tower fill zones where nozzle spacing is limited. Because the pattern remains filled rather than hollow, coverage stays consistent even when the target is offset from the nozzle centerline.
Narrow Angle Versus Wide Angle
A narrow angle generally produces a smaller theoretical footprint at the same distance. A wide angle covers a broader area but may need more clearance and overlap control. Neither is universally better. Compare both using the wide-angle vs narrow-angle full cone guide.
Flow, Pressure and Target Coverage
Higher system pressure does not automatically solve a coverage problem. The selected model, available pressure, supply stability, pipe losses and liquid condition must work together. Calculate the preliminary footprint, then verify distribution using the full cone spray distribution test.
Installation and Maintenance Notes
Mount the nozzle so the spray axis is perpendicular to the target unless the application specifically calls for an angled approach. Support long feed lines to avoid vibration at the nozzle connection, and fit a strainer sized to the orifice to reduce the risk of blockage from process solids. Inspect the orifice periodically for erosion, particularly in abrasive or high-solids service, since wear gradually widens the spray angle and reduces impact force. For thread engagement guidance, see this NPT thread reference.
Material and Maintenance
Review chemical compatibility and operating environment before choosing 303 stainless steel, 316 stainless steel or brass. If the liquid contains solids or forms deposits, include filtration, safe inspection access and a cleaning procedure that does not damage the orifice.
Frequently Asked Questions
Can the BBG narrow angle full cone nozzle handle viscous liquids? Higher-viscosity liquids typically need a larger orifice and lower pressure than the published water performance suggests; send the fluid data sheet for a specific recommendation.
What clearance does the nozzle need? Required clearance depends on the selected spray angle and target distance; use the selection checks above and confirm with the sales team before finalizing the layout.
