FAQs

1. What are the main differences between electric and pneumatic actuators?

Electric actuators use electricity for precise, automated control, while pneumatic actuators utilize compressed air for rapid response, often in hazardous environments. Electric actuators offer more precise control, while pneumatic actuators are typically less expensive and simpler to maintain.

2. How do I choose the right size actuator for my butterfly valve?

The actuator’s torque rating must exceed the valve’s operating torque requirements. Valve size, operating pressure, and fluid type influence the needed torque. Consult the valve and actuator manufacturer’s specifications for accurate sizing.

3. What are the common maintenance requirements for butterfly valve actuators?

Regular lubrication, visual inspections for leaks or damage, and periodic functional tests are essential. Specific maintenance schedules vary depending on the actuator type, operating conditions, and manufacturer recommendations.

4. Can butterfly valve actuators be used in hazardous areas?

Yes, many actuators are designed for hazardous environments, featuring explosion-proof certifications and materials resistant to corrosive substances. However, careful selection based on the specific hazardous area classification is crucial.

5. What are the advantages of using an automated actuator versus a manual one?

Automated actuators (electric or pneumatic) offer precise control, increased efficiency, remote operation capabilities, and improved safety by reducing the need for manual intervention in potentially hazardous environments. Manual actuators are simpler and less expensive, but lack the precision and automation of their automated counterparts.
