1. What is the ideal application for the Electric Cast Iron Flanged EPDM Butterfly Valve in water systems?
• The Electric Cast Iron Flanged EPDM Butterfly Valve is suitable for water treatment and industrial water pipelines requiring precise shutoff and flow regulation.
• The EPDM liner provides strong chemical resistance and reliable sealing.
• The electric actuator enables automated control and remote operation.
• The flanged cast iron body ensures stable installation and leak-free performance.
2. How to size a motorized flanged butterfly valve for HVAC or process systems?
• Calculate flow rate and system pressure drop to determine the required torque for the motorized butterfly valve.
• Match the electric actuator torque to valve size for complete and reliable closure.
• Confirm flange standard (ANSI/DIN/JIS) and ensure pipe compatibility.
• Choose an EPDM-seated butterfly valve for chilled or hot water circulation.
3. What are the key installation precautions for an electric flanged butterfly valve in industrial pipelines?
• Clean the pipeline before installing the electric flanged valve to prevent EPDM seat damage.
• Tighten flange bolts evenly to maintain proper alignment and sealing.
• Mount the electric actuator correctly on the ISO 5211 pad and connect suitable voltage.
• Verify the EPDM seat is compatible with the working medium.
4. How to maintain an electric actuated EPDM butterfly valve for long service life?
• Operate the electric butterfly valve periodically to prevent actuator and seat sticking.
• Inspect the EPDM seat for hardening or cracking under temperature cycles.
• Recalibrate actuator limit switches for precise disc movement.
• Check flange bolts and alignment to preserve sealing integrity.
