NPHH Series

NPHH

NPHH male inline one-piece full cone nozzles provide a compact, durable design for full cone distribution.

• NPHH series options within Full Cone Spray Nozzles—common in Cooling, Washing, Dust suppression.
• Select by spray angle and capacity/flow at pressure (often rated at 10 PSI for full cone); verify flow at your operating pressure.
• Choose inlet size (NPT) and materials to match your system, chemistry, and temperature.
• Compare related series: NPHSJ, NPGG, NPFGA, NPMFP, NPMGA, NPHH-SQ.

NPHH: Overview & Selection Tips

NPHH male inline one-piece full cone nozzles provide a compact, durable design for full cone distribution.

Key features

  • NPHH series: solid full-cone distribution for volumetric coverage
  • Serviceable cap-and-vane designs on select series for easier maintenance
  • Commonly sized using capacity at 10 PSI (verify for narrow-angle or large-volume models)
  • Corrosion-resistant materials available for aggressive environments

Typical uses for the NPHH series

  • Cooling
  • Washing
  • Dust suppression
  • Quenching
  • Fire protection

Selection notes

  1. Confirm required flow and available pressure at the nozzle.
  2. Choose spray angle to match coverage at your standoff distance and desired overlap.
  3. Confirm inlet size/thread type and orientation for your installation.
  4. Select materials and seals for chemical, temperature, and wear compatibility.
  5. Add strainers/filtration if clogging is a risk.

How to choose a full cone configuration

How to choose the right NPHH nozzle for your application

Use the NPHH series when you need performance aligned with Full Cone Spray Nozzles.
Typical applications include Cooling, Washing, Dust suppression, Quenching.
Start by confirming required flow (GPM/LPM) and available pressure at the nozzle.
Select spray angle to match coverage at your standoff distance, then confirm inlet size and material compatibility.
Many full cone catalog capacities are expressed at a standard reference pressure (often 10 PSI)—always verify flow at your actual operating pressure.

Frequently Asked Questions

Common questions about the NPHH series

What is the NPHH series used for?
NPHH full cone nozzles produce a solid circular pattern with uniform coverage from center to edge. They're used for washing, cooling, dust suppression, fire protection, and tank filling where complete coverage matters.
How do I calculate NPHH coverage diameter?
Use: Diameter = 2 × Spray Distance × tan(Spray Angle ÷ 2). For overlapping installations, space nozzles so patterns overlap by 25–30% to ensure uniform distribution across the target area.
What's the difference between vane-style and spiral full cone nozzles?
Vane-style nozzles offer more precise distribution but can clog with debris. Spiral designs (like NPHSJ) have larger free passage and resist clogging—better for dirty water, recycled fluids, or slurries.
What materials are available for NPHH?
NPHH nozzles are available in brass, 316L stainless steel, polypropylene, and PVDF. Select stainless for food/beverage applications; polypropylene or PVDF for chemical resistance.
How do I prevent clogging in NPHH nozzles?
Install upstream strainers with mesh finer than the nozzle orifice. Choose larger orifice sizes when possible. For dirty liquids, consider spiral full cone designs with their larger free passage.
What series are similar to NPHH?
Related full cone options include NPHSJ, NPGG, NPFGA, NPMFP, NPMGA, NPHH-SQ—compare by spray angle, capacity, and clog resistance.
