Fail Safe Valve Actuator
The AOX-Q Series Fail-Safe Electric Actuator is designed for precise control of valves that operate between 0° and 90°, including butterfly valves, ball valves, dampers, and plug valves. Engineered for safety and reliability, this fail safe actuator automatically returns the valve to a predetermined safe position during power failures, preventing hazardous situations in critical applications.
- Torque Range: Available from 50 to 6000 Nm, accommodating various valve sizes and types.
- Explosion-Proof Housing: Features an Exd II CT5 enclosure with IP67 protection, ensuring safe operation in explosive environments such as oil, gas, and chemical industries.
- Versatile Control Modes: Supports ON-OFF, modulating, and continuous control modes, with customizable options to meet specific operational requirements.
- Robust Construction: Built with die-cast aluminum and corrosion-resistant coatings for durability in harsh environments.
- Advanced Safety Mechanisms: The fail safe actuator includes a smooth reset process to safely return the valve to its designated position in emergencies.
- Environmental Compliance: Conforms to GB/4208-2017 standards for sealing protection, with optional IP68 rating for enhanced dust and moisture resistance.

FAQS
1. What is a fail-safe electric valve actuator?
A fail-safe electric valve actuator is designed to automatically move a valve to a predetermined safe position (either open or closed) when power is lost, ensuring safety in critical applications.
2. How does a fail-safe electric actuator work?
It typically uses stored energy, such as a spring mechanism or battery backup, to drive the actuator to the safe position when external power is unavailable, preventing equipment damage or unsafe conditions.
3. What are the two main types of fail-safe mechanisms?
Fail-safe mechanisms can be categorized into two types: spring-return systems that use mechanical energy storage and electrical backup systems that utilize batteries or capacitors to provide power during outages.
4. When should I use a fail-safe electric actuator?
These actuators are ideal for applications where safety is paramount, such as emergency shutdown systems in chemical plants, oil and gas facilities, and fire protection systems.
5. Can fail-safe electric actuators be operated manually?
Yes, many fail-safe electric actuators include a manual override feature that allows operators to control the valve manually in case of power failure or during maintenance.
6. What industries commonly use fail-safe electric actuators?
Fail-safe electric actuators are widely used in industries such as oil and gas, chemical processing, water treatment, HVAC systems, and fire protection for their reliability and safety features.
7. How do I select the right fail-safe electric actuator?
Consider factors such as the type of valve, required torque, environmental conditions, power supply options (AC or DC), and specific application requirements when selecting an actuator.
8. What maintenance is required for fail-safe electric actuators?
Regular inspections for wear and tear, cleaning to prevent dust buildup, checking battery levels (if applicable), and ensuring proper calibration are essential for maintaining optimal performance.
9. Are there safety certifications for fail-safe electric actuators?
Yes, many fail-safe electric actuators meet safety standards such as SIL (Safety Integrity Level) certifications, ensuring they perform reliably in critical applications requiring high safety standards.
10. What happens if the electric actuator fails during operation?
In the event of an actuator failure or power loss, the fail-safe mechanism will engage to move the valve to its designated safe position, minimizing risks and preventing hazardous situations.
