Preventing corrosion on pneumatic ball valve actuators is essential for maintaining functionality and extending service life. Corrosion, often caused by moisture, chemical exposure, or environmental contaminants, can degrade components and lead to operational failures.
✓
Material Selection
- Opt for actuators made from corrosion-resistant materials
- Stainless steel or specialized alloys are recommended
- Choose materials that withstand specific environmental conditions
- These materials naturally resist rust and chemical reactions
✓
Protective Coatings
- Apply high-quality paints, platings, or epoxy coatings
- Ensure coatings are evenly applied without cracks
- Reapply when signs of wear appear (chipping or fading)
- Even small gaps can allow corrosion to take hold
✓
Clean Environment
- Regularly remove dirt, debris, and chemical residues
- Use non-abrasive cleaners for actuator surfaces
- Avoid harsh solvents that damage coatings or seals
- Keep the area dry to prevent moisture buildup
✓
Proper Lubrication
- Use lubricants formulated to resist water
- Select lubricants that repel contaminants
- These form a protective film on metal surfaces
- Reapply according to manufacturer guidelines
✓
Seal Inspection
- Inspect seals and gaskets regularly
- Replace damaged or worn seals promptly
- Use materials compatible with operating environment
- Ensure tight barrier against external elements
✓
Monitor Exposure
- Monitor exposure to corrosive agents
- Implement safeguards in harsh environments
- Use protective enclosures or ventilation systems
- Reduce direct contact with corrosive elements
