Diaphragm Valves Uses & Applications

sed-diaphragm-valve-supplierProper diaphragm valves can allow for manual or automatic throttling, making them common in most industrial plants. Some models are best for water and wastewater controls, while straightway metal diaphragm valves can handle media with up to 50% solids, still avoiding clogs.

Plastic lined diaphragm valves are more common in chemical processing plants because of their ability to resist corrosion and dangerous fluids with minimal contamination. Food processing and pharmaceutical operations also turn to plastic lined diaphragm valves.
