Why Choose a Half Lined Butterfly Valve

A Half Lined Butterfly Valve offers excellent resistance to corrosive fluids while maintaining the strength of a metal valve body. Unlike conventional butterfly valves, the PTFE-lined sealing area minimizes direct contact between the process media and the valve components. Therefore, the valve delivers reliable sealing performance and extended service life.

Moreover, the lightweight structure simplifies installation and operation. Furthermore, the simple internal design reduces maintenance requirements and lowers operating costs. As a result, this valve is widely used for flow isolation and regulation in chemical processing applications.
