The diaphragm valve is specifically designed to control non-corrosive or generally corrosive media. The valve body surface can be unlined or lined with various rubbers, allowing selection based on application requirements. It is suitable for different working temperatures and fluid pipelines. The variety of lining materials provides good corrosion resistance and compatibility with various media. The valve body and cover are separated by the intermediate diaphragm, preventing the valve cover and stem components above the diaphragm from being exposed to the medium. The diaphragm valve is a specialized form of globe valve.
