FAQs That 80% Users Interest
1. What are the key considerations when selecting an electric actuator for industrial valve automation systems?
• Evaluate required torque and valve size to ensure the electric actuator can handle full open/close loads.
• Confirm ISO 5211 mounting compatibility between actuator and valve.
• Check IP65+ protection and temperature range for electric valve actuator in harsh environments.
• Choose between on/off or modulating control for precise integration with automation systems.
2. How does an electric actuator compare to pneumatic or hydraulic systems?
• Electric actuators eliminate air or fluid systems, reducing energy use and maintenance.
• Provide precise and repeatable positioning for accurate flow control.
• Offer cleaner operation with no leaks, ideal for sterile or indoor applications.
• Pneumatic options may still perform better in ultra-fast or high-cycle applications.
3. What maintenance practices extend the service life of an electric actuator?
• Inspect electrical connections, seals, and gear alignment regularly.
• Keep the motorized actuator clean and protected from moisture or dust.
• Test manual override periodically to ensure operation during power loss.
• Watch for unusual noise or vibration indicating wear or misalignment.
4. Can an electric actuator be used outdoors or in hazardous environments?
• Use models with ATEX or explosion-proof certification for hazardous areas.
• Ensure enclosure rating of IP65 or higher for outdoor use.
• Select corrosion-resistant materials for chemical or marine applications.
• Confirm manual override and feedback remain reliable in extreme conditions.
5. What are common causes of electric actuator failure and how to prevent them?
• Undersized torque capacity leads to incomplete valve movement.
• Poor alignment increases gear stress and reduces service life.
• Lack of protection allows corrosion or electrical faults.
• Overuse beyond rated duty cycle causes overheating or mechanical wear.
