FAQs That 80% Users Interest
1. What factors matter most when selecting an actuator for an automated butterfly valve system?
• Choose an actuator with torque output 1.2–1.5× higher than the valve’s required torque.
• Confirm the control signal type matches your automation setup.
• Use ISO 5211 mounting standards for actuator compatibility.
• Ensure the Electric Cast Iron Wafer EPDM Butterfly Valve fits your system’s pressure and temperature conditions.
2. How should a wafer-style butterfly valve be installed for water or HVAC pipelines?
• The electric wafer butterfly valve must be centered between flanges and tightened evenly.
• Match the flange class to prevent leaks and seat distortion.
• Test actuator operation before commissioning.
• Leave space for actuator wiring and maintenance access.
3. Is an EPDM-seated valve suitable for wastewater and light chemical applications?
• The EPDM-lined electric valve seals effectively for water and mild chemicals.
• Avoid use with strong acids, solvents, or high-temperature steam.
• Confirm the cast iron body and disc materials are compatible with the medium.
• Use an actuator with an IP67 enclosure for wet or corrosive environments.
4. What are the advantages of using an electric actuated butterfly valve instead of a manual type?
• The motorized cast iron butterfly valve enables remote automation and precise control.
• Compact wafer design reduces space and simplifies installation.
• EPDM seat ensures tight sealing and low maintenance.
• Electric operation improves accuracy and process efficiency.
5. How can I fix performance issues in an electric wafer butterfly valve?
• Check actuator wiring, torque settings, and signal integrity.
• Inspect the EPDM seat for wear or debris.
• Correct flange misalignment that causes vibration or noise.
• Keep the electric actuated valve housing sealed and clean.
