- For electropolished spray balls, the flow rate is approx. 15 – 20 % higher than stated in the table.
- Recommended operating pressure 1.0 to 2.5 bar g at the spray ball inlet. Guide value for cleaning liquid: 30 to 50 l/min per metre of tank circumference.
- 3A: After welding in, the spray balls must remain accessible for inspection and cleaning (3A Standard 78).
