Product Overview

 

Electric Actuated Butterfly Valve is an industrial automation valve designed for reliable shut-off and flow regulation in pipeline systems. It combines a butterfly valve and an electric actuator, enabling remote control, automated operation, and integration with PLC/DCS systems.
This product is widely used in water treatment, HVAC, chemical processing, and industrial automation systems where stable performance, remote operation, and long service life are required.
Compared with manual and pneumatic valves, electric actuated butterfly valves offer better positioning accuracy, easier system integration, and reduced maintenance requirements over long-term operation.

 

 
 
High-Performance Butterfly Valve

 

Verified Engineering Application Cases

Our electric actuated butterfly valves have been supplied for international industrial projects under the following verified application categories:
 

Municipal Water Treatment Project (Middle East, 2023)
DN600 PN16 valves used for main pipeline isolation and SCADA-based remote control system integration.
 

Commercial HVAC System Project (Central Europe, 2022)
DN200–DN400 valves installed in chilled water circulation systems for flow regulation and energy efficiency control.
 

Chemical Processing Plant Upgrade (Southeast Asia, 2024)
PTFE-seated electric butterfly valves used in corrosion-resistant pipeline systems handling chemical media.

 

Engineering Selection Logic
 

Electric actuated butterfly valve selection is typically based on the following engineering factors:

Pipeline diameter (DN size)

Working pressure (PN/Class rating)

Medium type (water, gas, corrosive chemicals)

Flow control requirement (On/Off or modulating)

Temperature range

Actuator torque requirement based on pressure differential

 

PTFE seats are recommended for corrosive media, while EPDM is suitable for water and HVAC systems. For high-cycle automation systems, modulating actuators with feedback signals are recommended.

FAQ

 

Q: What is an electric actuated butterfly valve used for?

A: Electric actuated butterfly valves are used for automatic flow control and shut-off in pipeline systems. They are commonly applied in water treatment, HVAC systems, chemical processing, and industrial automation where remote control or centralized system integration is required.

Q: What is the difference between On/Off and Modulating electric actuators?

A: On/Off actuators are used for fully open or fully closed operation. Modulating actuators allow precise position control (e.g., 4–20mA or 0–10V signal) for flow regulation and process control applications.

Q: How do I select the correct electric butterfly valve size?

A: Valve size is selected based on pipeline diameter (DN), flow rate, and pressure conditions. Proper actuator torque must also be calculated based on medium type, pressure differential, and valve size.

Q: Can electric actuated butterfly valves be used for corrosive media?

A: Yes. For corrosive media, PTFE or Viton seat materials and stainless steel discs are recommended to ensure chemical resistance and long service life.

Q: How long is the delivery time?

A: Standard delivery time is 7–30 days depending on order quantity and customization requirements.
