API609 Concentric Butterfly Valve

The structural feature of the API 609 concentric butterfly valve is that the valve stem axis, the center of the butterfly plate, and the center of the valve body are aligned. The API 609 concentric butterfly valve has relatively low sealing performance requirements in terms of structure and operation. To overcome issues of extrusion and scraping and to ensure sealing performance, the valve seat of the API 609 concentric butterfly valve is typically made of elastic materials such as rubber or polytetrafluoroethylene, making it a soft-sealing butterfly valve. This results in temperature limitations during use.
