FITOK needle valves for shut-off and flow control in instrumentation and process systems handling gases and liquids. This section includes individual design series; selection depends on the stem and seat design, body material, seals and required connections.
Key features
- Control and shut-off: select the stem tip and seat for the required function.
- Different designs: each series has its own connections, seals and operating limits.
- Analytical assemblies: selected configurations with SilcoNert coating.
Technical data and configurations
- Coated ND valves: the catalogue specifies coating all wetted metallic components; this scope does not apply automatically to every series.
Selection information
- Tell us the fluid, operating pressure, temperature and required flow rate.
- Select a suitable series for the application, such as NB, ND/NDH, NF/NFH or NG/NGH.
- Operating limits vary with materials and configuration; there is no single maximum pressure applicable to the entire category.
For sampling and analytical systems, ask about a suitable valve and the availability of SilcoNert 2000 coating. Our sales team can help determine the exact type, connections and ordering code.
