The clamp butterfly valve is known for its simple structure, compact size, and lightweight design, making it ideal for a wide range of industrial applications. It only consists of a few components and can be opened or closed quickly by rotating just 90 degrees, which makes the operation very straightforward. The valve offers excellent fluid control characteristics, as the pressure drop across it is minimal when fully open, since the thickness of the disc is the only resistance to flow.
There are two types of sealing available: elastic soft seal and metal seal. The elastic soft-sealing type can either be integrated into the valve body or attached to the disc itself. This flexibility ensures that the valve can meet different sealing requirements based on the application.
