Selection
Q: How do I choose the right nozzle type for my application?
A: Start with the fluid, required flow rate, available pressure and desired spray pattern (full cone, hollow cone, flat fan, etc.). Compare these against the nozzle family’s published flow-pressure data before selecting a specific model. Our team can review your operating conditions and recommend a starting point.
Q: What information do you need to recommend a nozzle?
A: Fluid type and viscosity, available pressure, required flow rate or coverage area, connection type, and any material or temperature constraints.
Q: Can one nozzle type replace another if I already have infrastructure in place?
A: Sometimes, but connection thread, spray angle and flow rate all need to be checked against the existing system before substituting a different nozzle family.
Materials
Q: What materials are your nozzles available in?
A: Brass, stainless steel, carbon steel, PVC, CPVC, polypropylene and PVDF, depending on the product line. Material choice depends on the fluid’s chemical compatibility, operating temperature and pressure.
Q: How do I know if I need a plastic nozzle instead of metal?
A: Plastic nozzles (PVDF, PP) are typically selected for corrosive or highly acidic/alkaline fluids where metal nozzles would degrade quickly. Check chemical compatibility charts for your specific fluid before choosing.
Q: Can nozzles be supplied with material certificates?
A: Yes, where required — confirm this requirement when requesting a quote.
Customization
Q: Can Jeltecn produce custom spray angles or flow rates?
A: Yes — custom orders are reviewed against your specific operating conditions before a design is confirmed.
Technical & Troubleshooting
Q: Why is my nozzle clogging frequently?
A: Common causes include fluid contamination, an undersized orifice for the particulate size present, or incorrect filtration upstream of the nozzle. Review your filtration and particulate size against the nozzle’s rated orifice size first.
Q: How do I calculate header spacing for uniform coverage?
A: Spacing depends on the nozzle’s spray angle and the distance from the header to the target surface — closer spacing is needed for narrower spray angles or shorter throw distances.
