Product Overview

Electric Flanged Butterfly Valve is an industrial automation valve designed for reliable flow control in pipeline systems. It integrates a flanged butterfly valve with an electric actuator, enabling remote operation, precise regulation, and automatic on/off control.
It is widely used in municipal water treatment, HVAC systems, industrial automation, and process pipelines requiring stable long-term operation.

Key Features

Compact structure suitable for limited installation space
Electric actuator for remote and automated operation
Bubble-tight sealing performance for reliable shutoff
Bi-directional sealing design for stable pressure performance
ON/OFF and modulating control options available
Manual override for emergency operation
Long service life with low maintenance requirements
Compatible with PLC / DCS automation systems

Engineering Application Experience

Our electric butterfly valves are widely used in real engineering environments, including:

Municipal water treatment and distribution systems
HVAC automation systems in commercial buildings
