Flange Butterfly Valve With Electric Actuator

Core Components of Electric Actuated Butterfly Valves

  ● Flanged Ends: Facilitate connection to industrial piping systems, ensuring high-strength sealing and pressure resistance.

  ● Butterfly Valve Body: Typically made from materials such as stainless steel, ductile iron, or PVC, making it suitable for various water qualities and corrosive environments.

  ● Electric Actuator: Controls valve opening and closing via electrical signals, enabling automated remote control; can be integrated into PLC or SCADA systems.
