The diaphragm valve is specifically designed to control non-corrosive or generally corrosive media. The valve body can be unlined or lined with various types of rubber, offering a range of options for different applications. It is suitable for use in fluid pipelines across a variety of working temperatures. The diverse lining materials provide excellent corrosion resistance and are compatible with multiple media types. The valve body and cover are separated by an intermediate diaphragm, which prevents the valve cover and stem components above the diaphragm from being eroded by the media. The diaphragm valve is a unique variant of the globe valve.
