A quick video showing the basic operation of a metal body, diaphragm valve for industrial applications.

The video illustrates how the metallic lower valve body is machined for a smooth controlled flow characteristic, and how the elastomer diaphragm is controlled by the liner movement of the valve stem. Full open, full closed, or proportional flow is controlled by the relationship of the valve diaphragm and valve body.

Metal body diaphragm valves are available in many metal alloys such as brass, cast steel, and 316 stainless steel, with many different elastomers including EPDM, PTFE and Viton.

These valves are great for inert and corrosive liquid and gaseous media, are highly resistant to chemicals, are insensitive to particulate media and offer a compact design (ideal when space is at a premium).
