الأسئلة الشائعة التي تهم مستخدمي طراز 80%
1.What steps help prevent actuator or seal failure in the motorized cast iron EPDM butterfly valve?
• Match actuator torque to valve requirements to avoid motor overload or wear.
• Ensure the EPDM liner is compatible with fluid type and temperature range.
• Align the ISO 5211 mounting pad and stem coupling correctly to prevent disc misalignment.
• Inspect actuator housing regularly to prevent moisture or dust ingress.
2.How does the cast-iron body and EPDM seat affect performance of the electric actuated butterfly valve?
• The cast iron housing provides strength and durability for HVAC and water systems.
• The EPDM seat is suitable for water, mild chemicals, and air but not strong acids or solvents.
• The combination supports moderate pressure and temperature with reliable sealing.
• Alternative materials are recommended for seawater, abrasive, or high-temperature media.
3.What installation issues should be avoided for the wafer-type motorized butterfly valve?
• Install in the correct flow direction to prevent seat or disc damage.
• Leave space for actuator wiring and manual override access.
• Avoid oversizing; correctly sized valves improve control and extend actuator life.
• Check flange flatness and gasket condition to prevent leakage at the wafer interface.
4.How does the electric actuator improve efficiency of the automated cast iron EPDM butterfly valve?
• Enables remote or modulating control to reduce manual operation.
• Multi-voltage design allows easy integration into automation systems.
• Calibrate limit switches and position feedback for accurate valve operation.
• Keep the manual override accessible for safe use during power failure.
