3. Material of Main Components (F321 Material)

Note: F321 (1.4541) is a titanium-stabilized austenitic stainless steel, offering good resistance to intergranular corrosion after heating.

No. Part Name Material Name (EN/DIN) Material Grade (AISI/UNS) Remarks
1 Body X6CrNiTi18-10 F321 / 321 Investment Casting or Forged
2 Body Cap / End Piece X6CrNiTi18-10 F321 / 321 Same as body material
3 Ball X6CrNiTi18-10 F321 / 321 Mirror-polished
4 Stem X6CrNiTi18-10 F321 / 321 Blow-out proof design
5 Seat Ring (Seal) PTFE / RPTFE / PEEK / See Section 7
6 Stem Packing Flexible Graphite / PTFE / Anti-static optional
7 Gasket Flexible Graphite + SS / Fire-safe design optional
8 Stud Bolts A2-70 Stainless Steel 304 Standard
9 Nuts A2-70 Stainless Steel 304 Standard

4. Technical Features

  • Design Feature: Adopts DIN F4 short face-to-face dimension. Compared to the standard DIN F1 length, it offers a shorter installation length and lighter weight, ideal for space-limited applications.

  • Material Advantage: F321 (1.4541) contains Titanium, which effectively prevents the precipitation of chromium carbides in the temperature range of 430°C – 800°C. It offers better welding characteristics and high-temperature resistance compared to 304/316.

  • Anti-Static Device: Anti-static springs can be installed between the ball and stem (in accordance with DIN 3357).

  • Fire-Safe Design: Optional fire-safe design available (in accordance with API 607 / ISO 10497).

5. Dimensions (Reference: DIN 3202 F4)

Note: Values depend on PN rating. Typical reference values (Unit: mm). Please confirm dimensions based on actual pressure rating.

Low-Pressure Seat Test Air 6 bar 6 bar EN 12266-1

7. Optional Configurations

  • Seat Material: PTFE (Standard), RPTFE (Glass-filled), PEEK (High-Temp), Metal (Wear-resistant).

  • Pressure Rating: PN16, PN25, PN40.

  • Accessories:

    • Limit Switch Box (Position Indicator)

    • Solenoid Valve

    • Positioner

8. Remarks

  1. F321 Welding Note: If the valve body requires welding on-site, post-weld stabilization heat treatment is recommended to ensure resistance to intergranular corrosion.

  2. Cleanliness: For Oxygen or special media service, Degreasing and cleaning are required.

  3. Flow Direction: Floating ball valves are generally bi-directional.
