A flanged ball valve is a valve that controls the medium in pipelines through a flanged connection structure, with the core component being a sphere that completes the opening or closing action by rotating 90 degrees.

Definition and Structure

The ball of the globe valve is driven by the valve stem and rotates around the valve stem axis. The structure includes the valve body, ball, valve seat, and sealing components. The main connection method is flanged, suitable for horizontal installation.

Working Principle

When the sphere rotates 90°, the channel and valve seat sealing surface opens or closes, achieving the cutoff, distribution, and flow control of the medium. The flow path is unobstructed, with low fluid resistance, and operation is convenient.

Material and Application Range

The valve body material is typically cast steel or stainless steel, with sealing surface materials including plastic and metal. Suitable for temperature ranges from -196°C to 550°C and pressures up to 42.0 MPa. Compatible with mediums such as water, acids, and natural gas, commonly used in the oil, chemical, and power industries.
