Straight-through diaphragm valve

Diaphragm valves are stop valves that use a diaphragm as a closing member to seal the flow passage, cut off the fluid, and isolate the valve body cavity from the valve cover cavity. The diaphragm is usually made of elastic, corrosion-resistant, and non-permeable materials such as rubber and plastic. The valve body is often made of plastic, fiberglass reinforced plastic, ceramic, or metal lined with rubber. They are characterized by simple structure, good sealing and corrosion resistance, and low fluid resistance.
