Product Description
Features
The butterfly valve features an innovative design with a compact size and lightweight construction.
The disc is double eccentric, enabling quick opening and closing for easy operation.
The double eccentric disc design eliminates sliding friction between the disc and the sealing ring, enhancing wear resistance and extending the service life. It ensures reliable sealing and is easy to adjust.
Working Principle
By rotating the handwheel, the valve is operated through a worm gear transmission. This drives the stem and disc to rotate within a 90-degree range, allowing the valve to open or close, effectively controlling the flow of the medium.
Main Parts Material
- Body: Ductile iron
- Disc: Ductile iron/Cast steel
