Designed and manufactured using a new structural form welded between a centerline butterfly plate and a short structural steel plate, it has a compact structure, light weight, easy installation, low flow resistance, large flow capacity, and avoids the impact of high-temperature expansion. It is easy to operate
No connecting rods, bolts, etc. inside, reliable operation, and long service life. Can be installed at multiple workstations, unaffected by medium flow direction
Here Is The Basic Structure Of Electric Butterfly Valve:
Ductile Iron Flanged Body
The valve features a robust flanged-style body made of ductile iron. It has flanges on both ends, allowing for easy installation and connection to the pipeline using bolts and gaskets.
Butterfly Disc and Stem
The valve incorporates a butterfly disc, also known as a butterfly plate, which is attached to a stem. The disc rotates within the valve body to control the flow of fluid. The stem connects the disc to the actuator, enabling smooth and precise movement.
Electric Actuator
The valve is equipped with an electric actuator that provides automated control. The actuator receives signals from a control system to open or close the valve, allowing for remote operation and accurate positioning.
Sealing Mechanism
The valve includes a sealing mechanism, such as an elastomer or PTFE liner, to ensure a tight shut-off and prevent leakage when the valve is closed. The ductile iron construction enhances the sealing efficiency and durability.
Flanges for Mounting
The valve has flanges on both ends of the body, enabling easy installation and connection to the pipeline using bolts and gaskets. This design provides a secure and leak-free connection.
