The Jeltecn BB square full cone spray nozzle produces a filled square impact pattern for multi-nozzle headers, washing, cooling, quenching and process-liquid distribution. Use it when a rectangular area needs organized coverage and nozzle orientation can be controlled.
BB Square Full Cone Nozzle Data
| Series | BB square full cone |
|---|---|
| Spray angle range | 40°–115°, depending on model and operating conditions |
| Water pressure range | 0.3–10 bar, based on the published model table |
| Orifice range | 1.6–31.8 mm, depending on size |
| Capacity range | 0.93–1230 L/h for water across the listed model range |
| Material options | 303 stainless steel, 316 stainless steel or brass |
| Thread options | NPT or BSPT; male or female configurations by selected size |
| Connection sizes | 1/8 in. through 2-1/2 in. within the published range |
Ranges summarize the listed family, not one individual nozzle. Confirm the exact size, angle, flow and connection from the model table before ordering. Published flow data is for water; other liquids may require review.
When to Choose a Square Full Cone Pattern
- A rectangular target must be covered by a grid or spray header.
- The process needs liquid across the full impact area rather than mainly around the edge.
- Nozzle orientation can be fixed so adjacent square patterns remain aligned.
- Flow, pressure and spacing can be checked under the intended operating conditions.
For a circular target or a single-nozzle installation, a round full cone pattern may be easier to position. See the full cone spray nozzle guide before choosing the pattern family.
Header and Coverage Checks
- Confirm the available pressure at the nozzle inlet after pipe, filter, valve and elevation losses.
- Select the model flow required at that pressure.
- Estimate the footprint from spray angle and mounting distance.
- Align every square pattern in the same direction.
- Set preliminary spacing, then verify edge coverage and overlap.
- Check for pressure imbalance across the header.
- Inspect the installed pattern before production approval.
A calculated footprint is only a layout starting point. Use the spray distribution test method where uniformity is important.
Liquid and Material Information
Before selecting 303 stainless steel, 316 stainless steel or brass, provide the liquid composition, temperature and operating environment. Also identify viscosity, specific gravity and suspended solids. These conditions can change flow behaviour, compatibility, filtration and maintenance requirements.
Installation and Maintenance
- Confirm thread standard and sealing method before installation.
- Keep the square pattern orientation consistent across the header.
- Use filtration appropriate to the selected passage and liquid condition.
- Do not damage the orifice during cleaning.
- Monitor flow, pressure and pattern appearance for blockage or wear.
Information Required for a Quote
Send the target dimensions, nozzle-to-target distance, total flow, flow per nozzle, available pressure, liquid details, connection, material, quantity and any drawing requirements. If the nozzle replaces an existing model, include the reference designation and operating result.
