Electric Butterfly Valve - Cast Iron
The Cast Iron Electric Butterfly Valve is an efficient and cost-effective solution for automated flow control in various industrial and commercial applications. Constructed with a durable cast iron body and equipped with an electric actuator, this valve enables remote and precise operation of on/off or modulating flow control.
JUHAN’s electric butterfly valve commonly used in HVAC systems, water treatment, chemical processing, and general fluid control, this valve ensures long service life, easy maintenance, and compatibility with international flange standards (such as ANSI, DIN, or JIS).
High-Performance Materials & Engineering
Key Features of the High-Performance Butterfly Valve for enhanced durability and corrosion resistance. Key structural features include:
- ● Durable Body Material,Made of ductile iron for strength and corrosion resistance.
- ● Available in EPDM, NBR, or PTFE to suit various applications.
- ● CF8 (SS304), CF8M (SS316), and aluminum bronze for different media compatibility.
- ● Facilitates easy maintenance and extended service life.
- ● Two-piece shaft disc design reduces turbulence and improves flow efficiency.
Working Principle
An electric butterfly valve operates by using an electric actuator to control the rotation of a disc inside the valve body. The disc is mounted on a central shaft and rotates to open or close the flow path within the pipeline. When the electric actuator receives a signal (either on/off or modulating), it drives the shaft, causing the disc to rotate.
- ● In the fully open position,the disc is parallel to the flow direction, allowing fluid to pass through with minimal resistance.
- ● In the closed position, the disc is perpendicular to the flow, creating a tight seal that blocks the passage of fluid.
Electric actuators can be configured for two-position control (open/close) or modulating control, where the disc angle adjusts precisely to regulate flow rate based on input signals such as 4–20 mA or 0–10 V.
