DIN F4 Short Pattern Floating Ball Valve

Technical Data Sheet

1. General Information

2. Design Standards & Specifications

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.

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.

6. Test Pressure (Example for PN16 / PN40)

7. Optional Configurations

• Seat Material: PTFE (Standard), RPTFE (Glass-filled), PEEK (High-Temp), Metal (Wear-resistant).
• Penilaian Tekanan: PN16, PN25, PN40.
• Aksesori:
• Limit Switch Box (Position Indicator)
• Solenoid Valve
• Positioner
• Gearbox (Worm Gear)

8. Teguran

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. Arah Aliran: Floating ball valves are generally bi-directional.
