Pneumatic Actuator Maintenance Guide
To ensure reliable operation and minimize air loss, follow these key measures:
1. Seal Maintenance & Selection
- Use high-quality seals (e.g., NBR, FKM, or polyurethane) compatible with operating temperatures and pressures
- Replace worn O-rings, piston seals, and shaft seals during routine maintenance
2. Proper Lubrication
- Apply silicone-based or synthetic lubricants to seals to reduce friction and wear
- Ensure lubricants are compatible with seal materials to prevent degradation
3. Air Supply Quality
- Use clean, dry air (ISO 8573-1 Class 3 or better) to prevent moisture-induced corrosion or seal damage
- Install filters, regulators, and lubricators (FRL units) to maintain optimal air conditions
4. Correct Installation & Alignment
- Ensure proper mounting to avoid misalignment, which can stress seals
- Tighten fittings and connections securely but avoid over-torquing
5. Leak Detection & Testing
- Perform regular leak tests using soap solution or ultrasonic detectors
- Monitor air consumption for unexpected increases indicating leaks
6. Use of Locking Mechanisms (Optional)
- For neutral-position stability, consider actuators with pneumatic or mechanical locks to prevent drift
Applications:
Ideal for process control, safety systems, and precision throttling where air efficiency is critical.
Note:
Regular inspection and preventive maintenance are essential for long-term leak-free operation.
