Diaphragm Control Valves are engineered with a flexible diaphragm at their core, which is instrumental in the regulation of fluid flow. When the diaphragm is actuated by the connected stem, it flexes, thereby altering the flow area and effectively controlling the rate of fluid passage. These valves stand out for their suitability in applications that demand high standards of cleanliness or involve the handling of abrasive and corrosive fluids.
