Two-piece and three-piece options
TW Series Ceramic Misting Nozzles
Select the construction and TW model together. Match the nozzle to the connection and operating conditions, and specify whether you need the nozzle body, mounting base or a complete assembly.
Two-piece and three-piece options
“Two-stage” and “three-stage” refer to the assembled construction, not pressure stages. TW3010 belongs to this series; it is not a separate nozzle family.
Two-piece construction
Ceramic orifice and spring shutoff assembly without the additional internal screen shown in the three-piece configuration.
Three-piece construction
Adds an internal screen ahead of the ceramic orifice. This screen does not replace upstream filtration, water treatment or routine cleaning.
Representative construction photographs, not exact-model photographs of every TW option.
Select by the exact supplied configuration. The number of sections alone does not establish flow, droplet size, clogging resistance or service life, and does not make the configurations interchangeable.
TW models and orifice sizes
The model table identifies orifice options, not a stock list of every construction/model combination. Confirm construction availability, thread standard, pitch, sealing seat and the pressure–flow data for the quoted version.
| TW model | Orifice (mm) |
|---|---|
| TW1010 | 0.10 |
| TW1510 | 0.15 |
| TW2010 | 0.20 |
| TW3010 | 0.30 |
| TW4010 | 0.40 |
| TW5010 | 0.50 |
| TW6010 | 0.60 |
| TW7010 | 0.70 |
| TW8010 | 0.80 |
For the TW8010 / 0.80 mm option, request pressure–flow data for the specified construction before sizing the pump.
Competitor catalogue flow reference by orifice size
The TW-to-NM pairing is a reference crosswalk, not product equivalence. These figures come from the historical Normist hex-series catalogue with stainless-steel 316 orifices. They are not measured or guaranteed flow values for this ceramic TW series. 50, 70 and 100 bar are source catalogue conditions, not TW rated or maximum pressures. Do not use them as permission to operate a TW nozzle at these pressures or assume equal flow for two-piece and three-piece constructions.
On smaller screens, scroll the table horizontally to see all source pressure columns.

TW8010 is absent from the source flow table; no estimate or extrapolation is provided.
Source: Normist catalogue, PDF page 61, printed page 118. Fluid, temperature, tolerance and the complete test method are not fully specified in the source table. Confirm actual supplied-product data before pump or system sizing.
Specify the components you need
A nozzle body, mounting base and assembled combination are different supply items. Identify the required construction, model and connection in the quotation; a base shown in an assembly photo is not automatically included.
System selection and maintenance
Request a nozzle quotation
Send the model, construction, quantity, connection details and intended operating conditions. If the thread or assembly is unclear, include a reference photo for review. The catalogue reference table is not a guaranteed quotation specification.
