Component Specifications

Definition
The nozzle body or housing is the primary structural component of a nozzle assembly, designed to contain internal flow channels, support internal components (such as orifices, swirl plates, or atomizers), provide mounting interfaces, and withstand operational pressures and environmental conditions. It serves as the pressure vessel that directs fluid from the inlet to the discharge orifice while maintaining structural integrity.
Working Principle
The nozzle body functions as a pressure-containing vessel that channels fluid from the inlet connection through internal passages to the discharge orifice. It maintains structural stability under pressure, provides sealing surfaces for gaskets or O-rings, and often incorporates features for mounting, alignment, and connection to fluid supply systems. The internal geometry may include flow-straightening sections, pressure chambers, or swirl chambers depending on the nozzle type.
Materials
Typically manufactured from corrosion-resistant materials: stainless steel (304, 316), brass, aluminum alloys, engineered plastics (PTFE, PEEK, polypropylene), or specialty alloys for high-temperature applications. Material selection depends on fluid compatibility, pressure requirements, temperature range, and environmental conditions.
Technical Parameters
  • Weight 0.1-5 kg (depending on size/material)
  • Surface Finish Ra 0.8-3.2 μm for sealing surfaces
  • Pressure Rating 50-5000 psi (depending on design)
  • Connection Types NPT, BSP, flange, quick-connect
  • Mounting Options Threaded, flange, clamp, welded
  • Temperature Range -40°C to 400°C
Standards
ISO 2852, DIN 11851, ASME B16.5, ISO 9001

Frequently Asked Questions

What is the difference between nozzle body and nozzle housing?

The terms are often used interchangeably, but 'body' typically refers to the main structural component containing flow passages, while 'housing' may include additional protective or mounting features. In practice, both describe the primary pressure-containing structure of the nozzle assembly.

How do I select the right material for a nozzle body?

Consider fluid compatibility (chemical resistance), operating pressure and temperature, corrosion requirements, sterilization needs (for food/pharma), and cost. Common choices: stainless steel for general industrial use, brass for lower pressures/costs, plastics for chemical resistance, and specialty alloys for extreme conditions.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
